The online errata list can be found there on the World Wide Web at http://pdsimg.jpl.nasa.gov/ This file, ERRATA.TXT, contains release notes and errata concerning the MESSENGER MDIS EDR archive. During the course of the MESSENGER mission the MDIS science team may update previously released data products or documentation; for example, updates may occur due to changes in calibration data or procedures. Updates will be reported in this file. Older versions of data and documentation will not be retained in the archive. Section A of this file contains an entry for each MESSENGER release with general information about the contents of the release, in order from newest to oldest. Updates to previously released files are reported in these entries, along with any known errata. Section B of this file contains general notes, if any, concerning the archive as a whole. ******** SECTION A ******** RELEASE NUMBER: 14 RELEASE DATE: 2015-10-09 DATA COVERAGE: 2014-09-18 to 2015-04-30 (Mercury Orbit Year 4, Mercury Orbit Year 5) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None No known errors or variances. -------------------------------------------------------------------------- RELEASE NUMBER: 13 RELEASE DATE: 2015-03-06 DATA COVERAGE: 2014-03-18 to 2014-09-17 (Mercury Orbit Year 4) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None No known errors or variances. -------------------------------------------------------------------------- RELEASE NUMBER: 12 RELEASE DATE: 2014-09-05 DATA COVERAGE: 2013-09-18 to 2014-03-17 (Mercury Orbit Year 3) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None No known errors or variances. -------------------------------------------------------------------------- RELEASE NUMBER: 11 RELEASE DATE: 2014-03-07 DATA COVERAGE: 2013-03-18 to 2013-09-17 (Mercury Orbit Year 3) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None No known errors or variances. -------------------------------------------------------------------------- RELEASE NUMBER: 10 RELEASE DATE: 2013-09-06 DATA COVERAGE: 2012-09-17 to 2013-03-17 (Mercury Orbit Year 2) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS EDR All MDIS EDRs have been updated to include the updated TWIST_ANGLE values which are now in compliance with the MDISEDRSIS. -------------------------------------------------------------------------- RELEASE NUMBER: 9 RELEASE DATE: 2013-03-08 DATA COVERAGE: 2012-03-26 to 2012-09-17 (Mercury Orbit Year 2) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None New MDIS EDRs include updated TWIST_ANGLE values which are now in compliance with the MDISEDRSIS. Previously delivered EDRs will be regenerated and updates included in a later delivery. -------------------------------------------------------------------------- RELEASE NUMBER: 8 RELEASE DATE: 2012-09-07 DATA COVERAGE: 2011-09-18 to 2012-03-25 (Mercury Orbit, Mercury Orbit Year 2) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None The PDS label portions of the EDR files are being padded with null characters (0x00) rather than space characters (0x20). Although the NASAView software displays the files correctly, this may cause problems for other software. The problem will be corrected in a future release. It should be noted that the values for the TWIST_ANGLE keyword in the labels range between -180 and +180 degrees, inclusive. Negative values should be expected and are valid. -------------------------------------------------------------------------- RELEASE NUMBER: 7 RELEASE DATE: 2012-03-15 DATA COVERAGE: 2011-05-18 to 2011-09-17 (Mercury Orbit) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS EDR REASON FOR UPDATES: New data from orbital operations. Notes: New EDRs are included in this release. All EDRs through delivery 5 have been redelivered to incorporate new label formats, which are explained in the EDR SIS documents. These redelivered files can be distinguished by an updated softare version id. The INDEX.TAB file has been updated to 1) include an ending "/" for path names and 2) string fields are left justified and padded with trailing spaces. The PDS label portions of the EDR files are being padded with null characters (0x00) rather than space characters (0x20). Although the NASAView software displays the files correctly, this may cause problems for other software. The problem will be corrected in a future release. -------------------------------------------------------------------------- RELEASE NUMBER: 6 RELEASE DATE: 2011-09-15 DATA COVERAGE: 2009-10-15 to 2011-05-17 (Mercury Orbit Insertion + 2 Months) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS EDR REASON FOR UPDATES: New data from early Mercury orbit. Notes: New EDRs, not previously released, are included in this release. These EDRs include new label keywords, which are explained in the EDR SIS documents. These keywords are useful for data obtained while in orbit, but are less useful for previously released information. For this reason, the previous images with the new label values are not being released at this time. It should be noted that the values for the TWIST_ANGLE keyword in the labels range between -180 and +180 degrees, inclusive. Negative values should be expected and are valid. -------------------------------------------------------------------------- RELEASE NUMBER: 5 RELEASE DATE: 2010-03-15 DATA COVERAGE: 2008-10-21 to 2009-10-14 (Mercury Flyby 3) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS EDR REASON FOR UPDATES: Improvements to labels. Notes: All previously released EDRs have been released in this delivery. Labeling of EDRs was updated in response to an MDIS flight software upload in August 2009. Several additional items of housekeeping were added to the headers of downlinked images, and propagated into the EDR labels. The image data itself did not change. In conjunction with the new label items, the INDEX table and label file were changed to include several new fields and several new terms were added to the MESSENGER MDIS local data dictionary. The new LLD terms are: IMG_ID_LSB, IMG_ID_MSB, PIV_POS_MOTOR; the updated term is: PIV_GOAL. Details concerning these changes can be obtained from the MDIS EDR SIS document, located in the DOCUMENT directory. Consult the change log table for relevant sections of the document. Note that these new terms have not yet been incorporated into the PDSDD.FUL data dictionary file (contained on the CDR volume. The data dictionary file has not been updated and remains the same as in the previous release. -------------------------------------------------------------------------- RELEASE NUMBER: 4 RELEASE DATE: 2009-04-15 DATA COVERAGE: 2008-01-29 to 2008-10-20 (Mercury Flyby 2) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS EDR REASON FOR UPDATES: Label improvements. Notes: Lables were updated to include information on image statistics, such as minimum, maximum, and mean values. The image data itself did not change. -------------------------------------------------------------------------- RELEASE NUMBER: 3 RELEASE DATE: 2008-07-15 DATA COVERAGE: 2007-06-21 to 2008-01-28 (Mercury Flyby 1) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None.
