Simpson Stanford University ============================================================================== INTRODUCTION ============================================================================== This file contains an accumulation of corrections and notes for the Mars Global Surveyor Radio Science Team Raw Data Archive - Mars Mapping Phase. ============================================================================== CORRECTIONS AND NOTES ============================================================================== MORS_0401 CATALOG/INST.CAT contains embedded quotes (") in the description. thru These were removed and "in" (for inches) was substituted. MORS_0444 DOCUMENT/OPTG_SIS.TXT contains embedded degree symbols. Those have been removed and "deg" has been substituted. MORS_0401 With few exceptions (perhaps 4), the values for MISSION_NAME and thru INSTRUMENT_HOST_NAME in labels for SAK files are MORS_0450 "MARS_GLOBAL_SURVEYOR". This is an illegal value; double quotes or underscores are acceptable, but not both and not neither. MORS_0401 OPT/9063287A.LBL and SPK/9063287A.LBL describe prediction files. INSTRUMENT_HOST_NAME is MARS_GLOBAL_SURVEYOR_SIM rather than the usual "MARS GLOBAL SURVEYOR." MORS_0402 This volume contains 9066071A.TDF in the TDF directory. The file spans the boundary between the Orbit Insertion and Mapping phases of the mission. MORS_0403 The Volume ID of this CD was incorrectly set to MORS_403. MORS_0404 Extra copies of the following files appear on this CD. The BRO file is already on MORS_0403; the ODRs (and corresponding BROs) are on MORS_0405. BRO/90831707.PS1 ODR/90870932.ODR ODR/90871129.ODR ODR/90871244.ODR ODR/90871327.ODR ODR/90871525.ODR MORS_0405 90890705.ODR in the ODR contains Ka-Band data from HGA calibration activities. The following files in the ODR directory have incorrect two-digit years in the DSP headers. Labels have been corrected manually. 90870932.ODR 90871129.ODR 90871244.ODR 90871327.ODR MORS_0411 The high-gain antenna (HGA) azimuth gimbal became stuck late on 1999/105 or early on 1999/106. A full set of spacecraft engineering data for 1999/106 was not obtained until several days later. The original engineering data are in ECH/9106106A.ECH while the later version is in ECH/9106106B.ECH. There are corresponding versions of the CSV files. No additional data was found for either days 105 or 107. For several days following the HGA anomaly, radio occultations and tracking were spotty. Typically the spacecraft low-gain antennas were used, the transponder was in 2-way mode, and telemetry was on. MORS_0413 First CD containing Antenna Gimbal Kernel (AGK) files; files covering 1999-03-29 through 1999-04-28 were included on this volume. First CD containing Antenna SPK (ASP), Hinge CK (HCK), and Text Frame Kernel (TFK) files -- all in the CALIB directory. SIS changes covering the ASP, HCK, and TFK files were not completed in time to be included with this volume; see MORS_0414. MORS_0416 File AMD/9126127A.AMD (ORIGINAL_PRODUCT_ID = amdgen.99-127_2.out) has an incorrect STOP_TIME in the label. Stop time should have been 10:13:12.000. The error was corrected and a revised file (with the same ORIGINAL_PRODUCT_ID) became AMD/9126127B.AMD on MORS_0417. MORS_0418 File ERRATA.TXT in the root has two lines with 81 characters. MORS_0433 The label file for HEA/HEA9172A.PS1 is missing. MORS_0437 The label file for HEA/HEA9181A.PS1 is missing. MORS_0444 First CD containing MCT engineering channel table files. Files from 1999-068 through 1999-131 are availible, with more files availible on the following CDs. MCT files are currently being created for two engineering channels, M-0725 (AA5 system temperature) and M-0775 (AB5 system temperature). The format and content of OPTG files changed slightly in early August 1999. OPT/9214234A.OPT was in the original format; OPT/9214234B.OPT was identical except that it was in the new format. All OPTG files generated subsequently were in the new format. MORS_0445 Second CD containing MCT engineering channel table files. Files from 1999-132 through 1999-196 are availible. Beginning with the next volume, MORS_0446, the MCT files should be appearing up to date. These initial files had to be distributed over multiple CDs because each CD can hold no more than 256 files of a given type. MORS_0450 ODR/92432050.ODR has records missing at positions 5443, 5444, 8618, and 8619.
