PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT NOTE = "Errors or discrepancies identified on the Galileo Jupiter Orbital Operations Solid State Imaging Raw EDR CD-ROMs (volumes GO_0017 thru GO_0019)" PUBLICATION_DATE = 1998-09-01 END_OBJECT = TEXT END ERRORS AND/OR DISCREPANCIES ON GALILEO REDR CD-ROMs This document describes errors and discrepancies in specific images on this volume (e.g., gaps, CDS dropouts, saturated images, etc.) and previous volumes in the volume set. This document also describes standard processing methods developed particularly for handling Galileo Phase 2 data. Also included are newly identified errors or discrepancies on previous volumes of the Galileo Solid State Imaging Raw EDR CD-ROMs. Information relating to limitations, errors and discrepancies in the entire data set is included in the Limitations section of the DATASET.CAT file in the CATALOG directory. Contents of the file include: general information, VICAR Labels, PDS Labels, Index Table and Cumulative Index Tables.

Also included is information on processing. This mainly for the user's information. Due to a problem with the flight software, the exposure values in the images were being returned low by 4-1/6 milliseconds except for exposure numbers 1, 2, and 4. Software was modified to adjust image exposure values in the VICAR and binary labels to reflect actual exposure times. HIS images had a line shift of 1 line on the 2nd and 4th frame cycles and during extended exposures and OCM images. Software was modified to position the lines correctly. Multiple playback of images with different compression factors are not d together and each subsequent filename is incremented by 1. Smear and smear magnitude do not have valid values because the angular velocity is not available in the actual CK. Local Hour Angle keyword is not valid for Ring Images. Light Flood values are based on the predicted values received in the SNIP. It should be noted that the light flood for OCMs are "ON" for the 1st shutter event and "OFF" for all the others. The TARGET field in the IMGINDEX.TAB is limited to 10 characters, so in cases where the target name is too long, the string is truncated. For example, "NON_SCIENC" will appear for NON_SCIENCE calibration targets.
