1. INTRODUCTION

1.1 Content Overview

This Software Interface Specification (SIS) describes the form and content of the Raw Experiment Data Record Compact Disc - Read Only Memory (REDR CD-ROM).

The REDR CD-ROMs shall be generated by the Galileo Project in order to distribute the images acquired by the Solid State Imaging (SSI) camera to the scientists and later to the Planetary Data System (PDS).

A detached PDS label shall be included for each image. Documentation files shall be provided which inform the user about the organization and contents of each disk, the definition of the labels and also an index file containing information about all the images stored in the dataset.

All PDS label formats and documentation are based on the Planetary Data System Data Preparation Workbook (see reference 4). The VICAR label's format and documentation can be referenced in the VICAR User's Guide (see reference 5).

All data formats are based on the Planetary Science Data Dictionary Document (PSDD) and the Planetary Data System document DPW (see references 1 and 4) and are similar to the formats used in generating the Voyager CD-ROM set (see reference 2).

Section 1 of this document contains general information. Section 2 describes characteristics of the physical media (CD) used in transmitting REDRs, and Section 3 specifies their logical (media-independent) contents.

1.2 Scope

The specifications in this document apply to all REDR CD-ROMs that are produced during the Galileo mission.

1.3 Applicable Documents

2 INTERFACE CHARACTERISTICS

2.1 Operations Perspective

2.1.1 Data Source, Destinations, and Transfer Method

REDR CD-ROMs shall be produced by MIPS for distribution to the Galileo Project. MIPS shall use commercially available CD-ROM publishing software, which shall reside at MIPS, to produce premastered tapes for delivery and release to the mastering vendor for production of CD-ROMs. The mastering vendor will ship the discs to MIPS for distribution and archiving.

2.1.2 Generation Method and Frequency

The REDR CD-ROM data shall be generated by using a series of VICAR programs. The REDR data processing steps include: merging partial frames together, updating VICAR labels (optional), updating the Bad Data Value Label with bad data values (optional), applying blemish corrections to image data (optional), filling in missing data lines (optional), generating a PDS label and pre-mastering data to a CD-ROM.

The CD-ROMs shall be produced at the following rates: during cruise they shall be produced as rapidly as possible on a best efforts basis, during Jupiter Orbital Operations they shall be produced at the rate specified in the Image Processing Subsystem Functional Requirements Document.

2.2 Volume and Size

Each CD-ROM shall contain approximately 800 Galileo SSI images in the REDR format.

Each CD-ROM shall contain at most 650 Mbytes of data.

2.3 Interface Medium Characteristics

REDR CD-ROM physical characteristics shall conform to ISO-9660 industry standards [see reference 3].

2.4 Backup and Duplicate Copies

The CD-ROM contents shall be stored on magnetic disk until a validated master has been produced. REDR image data files, excluding the text and PDS labels, shall be retained on a CD write once at MIPS.

2.5 MIPS Label ID

Each REDR CD-ROM to be sent to the vendor will bear a label id using the following format:

PROJECT_SEQUENCE

PROJECT = GO_

SEQUENCE = sequence number consisting of four digits.

EXAMPLE = GO_0003

3 CD-ROM CONTENT AND FORMAT

This section describes in detail the format and content of the REDR CD-ROM.

3.1 Format

REDR CD-ROM data shall be formatted in accordance with Planetary Data System specifications [see references 1, 4]. The format is described below.

3.1.1 Disk Format

The REDR CD-ROM format shall be compatible with various computer systems including IBM PC, Apple Macintosh, Sun, Digital VAX. The REDR CD-ROM format shall be in accordance with ISO 9660 level 1 Interchange Standard [see reference 3], with file attributes specified by Extended Attribute Records (XARs) (logical blocks of 512 bytes), to provide a file system of directories, sub-directories, and data files. Computer systems that do not support XARs will either ignore them or append them to the beginning of the file. In the latter case, the user must ignore the first 512 bytes of each file.

3.1.2 File Formats

The following paragraphs describe file formats for the various kinds of files contained on the CD-ROMs.

3.1.2.1 Image Files

Image files (.IMG suffix) exist only in the target directories. The files contain a VICAR label, Binary Telemetry Header, Bad Label Header, a Binary Prefix and the imaging data. See the REDR SIS (Reference 7) for additional information regarding the image file data structure.

3.1.2.2 Document Files

Document files (.TXT suffix) exist in the root and document directories. They are ASCII files with embedded PDS labels. All document files contain stream files with ASCII carriage return and line feed characters at the end of each line. This allows the files to be read by the HFS, DOS, Unix, and VMS operating systems.

3.1.2.3 Tabular Files

Tabular files (.TAB suffix) exist in the index directory. Tabular files are ASCII files formatted for direct reading into many database management systems on various computers. All fields are separated by commas, and character fields are enclosed in double quotation marks ("). (Character fields are padded with spaces to keep quotation marks in the same columns.) Character fields are left justified, and numeric fields are right justified. The "start byte" and "bytes" values listed in the labels do not include the commas between fields or the quotation marks surrounding character fields. The records are of fixed length, and the last two bytes of each record contain the ASCII carriage return and line feed characters. This allows a table to be treated as a fixed length record file on computers that support this file type and as a normal text file on other computers.

All tabular files are described by detached PDS labels. The PDS label file has the same name as the data file it describes, with the extension .LBL; for example, the file IMGINDEX.TAB is accompanied by the detached label file IMGINDEX.LBL in the same directory.

3.1.2.4 PDS Label Files

PDS label files (.LBL suffix) are located in the target directories. They are descriptive labels [see reference 4 and paragraph 3.2.2] and are detached from their associated file. The PDS label file is an object-oriented file; the object to which the label refers (e.g. IMAGE, TABLE, etc.) is denoted by a statement of the form:

^object = location

in which the carat character (^, also called a pointer in this context) indicates that the object starts at the given location. The location denotes the name of the file containing the object, along with the starting record or byte number, if there is more than one object. For example:

^IMAGE_HEADER = ("7890R.IMG",1)

^IMAGE = ("7890R.IMG",3)

indicates that the IMAGE object begins at record 3 of the file 7890R.IMG, in the same directory as the detached label file. Below is a list of the possible formats for the ^object definition.

^object = n

^object = n<BYTES>

^object = ("filename.ext")

^object = ("filename.ext",n)

^object = ("[dirlist]filename.ext",n)

^object = ("filename.ext",n<BYTES>)

^object = ("[dirlist]filename.ext",n<BYTES>)

where

n	is the starting record or byte number of the object, counting from the beginning of the file (record 1, byte 1),
<BYTES>	indicates that the number given is in units of bytes,
filename	is the upper-case file name,
ext	is the upper-case file extension,
dirlist	is a period-delimited path-list of parent directories, in upper case, that specifies the object file directory (used only when the object is not in the same directory as the label file). The list begins at directory level below the root directory of the CD-ROM. '[dirlist]' may be omitted when the object being described is located either in the same directory as the detached label, or in a subdirectory named 'label' that is located in a higher level of the directory tree, typically the CD-ROM root itself.

All detached labels contain 80-byte fixed-length records, with a carriage return character (ASCII 13) in the 79th byte and a line feed character (ASCII 10) in the 80th byte. This allows the files to be read by the HFS, DOS, Unix, and VMS operating systems.

3.1.2.5 PDS Format Files

Format files (RLINEPRX .FMT and RTLMTAB.FMT) exist in the label directory. These files are PDS labels that describe the structure of the binary line prefixes and file headers of REDRs (RLINEPRX.FMT, RTLMTAB.FMT). They are descriptive label files [see reference 4 and paragraph 3.2.2] and are detached from their associated file.

3.2 Content

The following paragraphs describe the content of the CD-ROMs.

3.2.1 Directories

The REDR CD-ROM directory structure consists of one root directory, an index subdirectory, a document subdirectory, a catalog subdirectory, a calibration subdirectory, a label subdirectory, and subdirectories by target or activity of the REDRs.

Files in the root directory provide label and text describing the content and format of the REDR CD-ROMs. Files in the index directory provide a table of label items describing the observation of a respective REDR frame, and a PDS label which in turn describes the index table. The index table entry is generated after each REDR file is processed in the CD generation procedure. The index table on each CD-ROM shall only reflect those files contained on that CD-ROM, except for the final CD-ROM of each of the dataset, which shall contain a complete listing of the entire index table.

Files in the label, catalog, and document subdirectories are the same on all CD-ROMs and contain VICAR label and REDR binary header and line prefix information, detailed information about the mission, instrument and dataset, and applicable documents. Files in each of the target subdirectories consist of an REDR image file and an associated label file, organized in sub-directories by RIM count of the Spacecraft Clock (SCLK). The following tables describe the content and source of files in the REDR CD-ROM directories. (Source indicates group providing current version of file.)

3.2.1.1 Root Directory

The following table lists the files in the root directory.

3.2.1.2 Index Directory

The following table lists the files in the index subdirectory.

3.2.1.3 Label Directory

The label directory contains REDR binary line prefix and file header structural information in .FMT files. The following table lists the files in the label directory.

3.2.1.4 Document Directory

This directory contains the REDR VICAR image header descriptive information, bad data values of image binary header and a description of the PDS label.

3.2.1.5 Catalog Directory

This directory contains files describing the data set, instrument, project, etc.

3.2.1.6 Target Directories

The target directories contain the actual image data. The image data has been sorted by target body, e.g. EARTH, MOON, VENUS, etc. and the directories named accordingly. Within each target directory, the observations have been grouped by common RIM count of the Spacecraft Clock (SCLK). These subdirectories are named Crrrrrr, where the r's represent the first six of eight digits of the RIM count in the SCLK, that has been padded with preceding zeros. (e.g. [Venus.C001806] )

The REDR data and the matching detached PDS labels will be found within the RIM subdirectories, These files are named rrmmR.IMG, where rr is the remaining two digits of the RIM count, and mm is the MOD91 count in the SCLK. See the following table for examples and brief definitions of the REDR and PDS files.

3.2.2 Files

The contents of the REDR CD-ROM files are described in the following paragraphs. Paragraphs 3.2.2.2, 3.2.2.3, 3.2.2.4 list PDS labels which describe files VOLDESC.CAT, image files and the index table. Format files (.FMT) describe the structure of the binary header and line prefix. The keywords on the left are static; the values on the right are variable, except for the .FMT files.

NOTE: The labels listed below are not literally reproduced. For the exact structure of PDS labels refer to DPW [see reference 4].

3.2.2.1 Image Data Files

The Image Data Files are in the REDR format. See the above table for a brief definition of the format. See reference 6 for additional information.

3.2.2.5.3 BADDATA.TXT

This is a textual file that describes the structure and content of the bad data value header which follows the telemetry header and precedes the image records. (See Appendix B).

3.2.2.6 VICAR2.TXT

This is a textual file that describes the structure and content of the image header which precedes the telemetry header and precedes the image records. (See Appendix C).

Appendix A

The following table lists the support staff according to the information required by the user.

This section defines the format and contents of the binary labels used to store SSI bad-data values.

There are two parts to the binary label: the binary header, and the binary prefix. The binary header precedes the image data (as do the ASCII labels) and contains information which pertain to the entire image. The binary prefix precedes each image line and contains information specific to each line. Binary labels are created by adding the U_NLB and U_NBB keywords to the XVOPEN call. Binary labels are accessed from a file already containing them by adding the CONDITION, BINARY keywords to the XVOPEN call. Note that since VICAR programs do not normally include these keywords in their XVOPEN calls, binary labels are usually ignored and disappear when new versions of an image are created. Binary labels were originally designed to support the generation of Voyager EDRs. The binary labels are written in VAX compatible (least significant byte first) format.

The binary header consists of an arbitrary number of records. The first record contains ancillary telemetry information. The remaining binary header records contain bad-data information,stored as a sequence of "objects" in 16-bit integer format for EDRs and 8-bit integers for REDRs. The following types of objects have been defined:

These objects are used to encode the following bad-data types:

Single-pixel spikes are stored as single pixels, data drop-outs, saturated pixels, and Reed-Solomon overflow records are stored as line segments, and low-full-well pixels as column segments.

Note: For compressed image data, all pixels to the right of the first bit error will be corrupted. Since it is not possible to determine where this bit error occurs, the entire line is flagged as bad.

Each record will be in 16-bit integer data format and will contain only one type of object. The first three integers of each record contain the record ID, object code (CODE), and the number of objects in the record (N), respectively. The remainder of the record will contain a sequence of N objects. The maximum number of objects which can be stored on a record is a function of the EDR record length and object code. Full-frame and summation-mode EDRs have record lengths of 1800 bytes and 1000 bytes, respectively:

If more objects of a certain type exist, they are written on subsequent records. The records are not necessarily written in any particular order, although they must all precede the image line records.

Example 1: Let a binary header record contain the sequence of integers 6,1,3,211,104,322,111,401,233. The record contains single-pixel spikes (6) encoded as single-pixels (1). There are three objects encoded as line-sample coordinates: (211,104), (322,111), and (401,233).

Example 2: Let a binary header record contain the sequence of integers 4,2,2,110,216,105,789,420,381. The record contains saturated pixels (4) encoded as line segments (2). There are two objects. The first line segment is on line 110 and from sample 216 to 320. The second line segment is on line 789 and from sample 420 to 800.

Example 3: Let a binary header record contain the sequence of integers 5,3,2,299,710,91,521,72,729. The record contains low-full-well pixels (5) encoded as column segments (3). There are two objects. The first column segment is on sample 299 and from lines 710 to 800. The second column segment is on sample 521 and from lines 72 to 800.

The following is an example of a program which reads an image containing bad-data information, does something with this information, and outputs an image which does not contain any binary labels (all subroutines other than XV routines are fictitious):

COMMON/HDRREC/RECORDID,CODE,NOBJECTS,SPIX(2,448)!Binary header record

The following is the VICAR2.TXT file which describes the SSI VICAR label of the Galileo REDR images.

INTRODUCTION

This file describes the organization and content of the Galileo SSI flight
label for REDR and EDR images. This label is based on the Video Image
Communication and Retrieval (VICAR) image processing label standard. Label
items, their meanings and values, are described in this document.

VICAR LABEL STRUCTURE

The VICAR label is a string of ASCII characters consisting of free-field items
of the form "keyword = value" separated by spaces. It contains data set
description system information regarding the dimensions, organization and data
format. This information is written to the label with the following keywords:

LBLSIZE Size of the label in bytes
FORMAT Data format (byte, halfword, real, fullword, etc.)
TYPE Data set type (image, parameter, histogram, plot, etc.)
BUFSIZ Internal blocksize VICAR will use during input/output
DIM Data set dimension
EOL End-of-dataset label
RECSIZE Data set record size
ORG Data set organization:
BSQ - Band Sequential
BIL - Band Interleaved by Line
BIP - Band Interleaved by Pixel
NL Number of lines or records
NS Number of samples or record length
NB Number of bands or number of data planes
NBB Number of binary prefix bytes
NLB Number of binary header records
N1 Equal to NS
N2 Equal to NL for BSQ, NB for BIL and NS for BIP
N3 Equal to NB for BSQ, or NL for BIL and BIP
N4 Not used
HOST Type of computer used to generate the image.
INTFMT The format used to represent integers in the file.
REALFMT The format used to represent floating numbers.
BHOST Type of computer used to generate the binary information.
BINTFMT The format used to represent binary integers in the file.
BREALFMT The format used to represent binary floating numbers.
BLTYPE The binary label type. Currently not implemented.


The VICAR label also contains processing history information on the file
describing the application programs or procedures which have processed the
data set, the user parameters of the respective programs or procedures, the
user identification and processing date and time. The following VICAR label
items are used to describe history information for each program or procedure
executed:

TASK Program or procedure that has processed the data set
USER User identification
DAT_TIM Processing date and time
opt. items VICAR label items added by application program or
procedure listed under the respective task

GALILEO SSI FLIGHT LABEL

The following is the latest memorandum describing the SSI VICAR label for
Jupiter Orbiatal Operations (Phase 2) and retains Cruise (Phase 1)
information. The memorandum describes both the SSI Ground-Calibration label
and the Flight label. PDS labels contained in this CD-ROM data set are
flight labels.

INTRODUCTION: This memo documents the format and contents of the Galileo
SSI ground-calibration label and flight image label for both cruise
(Phase 1) and Jupiter Obital Operations (Phase 2). The purpose of these
labels and requirements for label maintenance are also addressed.

PURPOSE OF THE PROJECT LABEL: All digital images stored in standard VICAR
format are preceded by a picture label. The label consists of picture
descriptors and processing history information stored in ASCII.

Flight projects have traditionally designed special label formats to
identify the mission, spacecraft, instrument, target, and frame, and to
include various camera and image geometry information pertinent to the
interpretation of the image. The project labels are attached to each new
image received via the real-time system, or ground-calibration
tapes. Consequently, these labels normally precede all other labels.
This memo is concerned specifically with these project labels, and does not
address other labels added by VICAR or application programs during process-
ing.

During systematic and science processing, individual programs may extract
and use various image identifiers and camera parameters stored in the
label. The image geometry information included in the label is ignored
during processing, since more accurate information is available in the
project SEDR or SPICE files.

As each new version of an image is produced, the VICAR system will
automatically copy the picture label and add the program name, user name,
and date to the processing history. In addition, individual programs
may add processing information to the label.

The image label may be printed by executing LABLIST or LABEL-LIST on the
image. Unless a rigid file-name nomenclature is adhered to, this image
label is the only means of identifying an image stored on disk.

GALILEO SSI GROUND-CALIBRATION LABEL: The ground-calibration picture label
is generated by program VGLLOG, which reads tapes generated by the Galileo
Sensor Test Set (STS) and converts the file to standard VICAR image format.

Appendix 1 presents a brief description of each label item. The ground-
calibration label follows a convention used to support old label formats
originally used on the IBM (before 1984). The project labels are stored
as label items LAB01, LAB02, LAB03, etc. Each LABXX item consists of
a 72-character ASCII strings. The 71st character is a label type flag used
by some programs (e.g. MASKV) to control which labels are displayed or
printed. The last character in each string is a 'C' (for continue) or 'L'
(for last). However, note that the additional label item NLABS should be
used to indicate how many project labels are present.

GALILEO SSI FLIGHT LABEL: The flight label is in free format, with each
label item stored in the form "keyword=value". A brief description of each
label item is provided in Appendix 2 for Phase 1 and for Phase 2.

Summation-mode frames can be identified by their 2 1/3 frame rate and
15-1/6 frame rate (added for Phase 2). The majority of the label
items are generated by the Real-Time subsystem's Image-Builder program.
Label items DC, CAL, SO, BLM, IOF, CNV, and UBWC are added by GALSOS.
If the image is read from an EDR tape, label items EDRTAPE and EDRFILE are
added by GEDREAD. EDRTAPE and EDRFILE are no longer used with files
archived on CD-ROM.

When an image is map-projected, the following label items relating to
image geometry must be updated (by MAP3): SUNAZ, SMRAZ, SCAZ, NORAZ,
SMR, LAT, LON, HSCL, VSCL. This is not currently implemented.

The program LABLIST has been written to list the label items in a
standard format at the terminal or on hardcopy. (NOTE: See Appendix 2
for a complete list of Phase 2 label-items. At publication time, the
program LABLIST had not been modified to read and format the most recent
additions.) The following is the format for a Phase 1 image:

APPLICATION PROGRAM/LABEL INTERFACES: Label items may be stored, retrieved,
or deleted via subroutines XLADD, XLGET, or XLDEL, respectively. Subroutine
VIC1LAB may be used to retrieve all ground-calibration labels. The subroutine
ABLE86 will extract specific information from either flight or ground-
calibration labels and return the results in an array (e.g. filter position).
Note that programs that support more than one mission (e.g. Voyager and
Galileo) should not call ABLE86 directly, but use GETLABCON instead.

2) The SCET refers to the shutter center of the shutter event.
3) If the target is the ring-plane of Jupiter, label items LAT and
LON are replaced by RAD and LON.
4) Prior to JOI, MOFIBE was FIBE and ENCODING_TYPE was BARC.
5) TBPPXL, TPPLNE apply to BARC compression only.
6) QUANTIZATION_STEP_SIZE, QUANTIZATION_MATRIX_NAME,
TRUTH_WINDOW, ICT_DESPIKE_THRESHOLD and ZIGZAG_PATTERN apply to ICT
Compression only and are defaulted for Huffman (lossless) compressed
images. COMPRESION_RATIO, MINIMUM_COMPRESSION_RATIO, and
MAX_COMPRESSION_RATIO apply to ICT and Huffman only (lossless) images.
CUT_OUT_WINDOW applies to both ICT compression and BARC compression
7) HUFFMAN_TABLE applies to Huffman only (lossless) and ICT compression
images. Note that ICT compressed images are also HUFMAN compressed
but are identified as ICT.
8) NSTARS,STAR1,STAR2,STAR3,STAR4 and STAR5 apply to OPNAV images only.
9) All azimuth angles are measured clockwise from right in the image.
10) An image "size field" defines the location and size of an image area.
It consists of four numbers: starting line, starting sample, number of
lines, and number of samples. The origin of the image coordinate system
is at (LINE,SAMPLE)=(1,1) for the upper-left corner, with samples
increasing to the right and lines increasing downwards.
11) INA, EMA, PHA, HRA, SMEAR, HSCL, VSCL, LAT, LON, and RAD are for the
center of the image if all four corner lie on the target, otherwise
it is at the target center if visible, otherwise the image is scanned
at 20 pixel intervals for a point at highest resolution.
12) The J2000 coordinate system is used for all orientation calculations.

Application program label interface: Label items may be stored, retrieved,
or deleted via subroutines XLADD, XLGET, or XLDEL, respectively. Subroutine
VIC1LAB may be used to retrieve all ground-calibration labels. The subroutine
ABLE86 will extract data from either flight or ground-calibration labels and
return the values in an array. Note that programs intended for multimission
support should not call ABLE86 directly, but use GETLABCON instead.

When an image is map-projected, the following label items relating to image
geometry are updated by MAP3: SUNAZ, SMRAZ, SCAZ, NORAZ, SMRAZ, LAT, LON,
HSCL, VSCL. This is not yet implemented.
