Simpson Stanford University ============================================================================== INTRODUCTION ============================================================================== Errors and anomalies known at the completion of PDS peer review for this data set are listed below, ordered by volumes on which they appear. In most cases, these were not corrected on the affected volume; this list is your only warning. Files which apply to the entire data set (for example, files in the CATALOG, DOCUMENT, and INDEX directories) were corrected and included with the revised last volume in the data set (MORS_0156, Version 5). Users are encouraged to disregard the earlier versions of these files. MORS_0156, Version 5 also contains ECS, ENB, USO and files in the DOCUMENT directory which were not present on earlier versions of MORS_0156 or on earlier volumes; these new files apply to the entire Cruise period. The official end of the Cruise Phase has been defined as 1997-09-12; when this data set was assembled, the end date was understood to be 1997-09-02. If a complete understanding of Cruise data is required, users may wish to investigate the first few volumes in the MGS-M-RSS-1-MOI-V1.0 data set (for example volumes MORS_0201 through MORS_0205). ============================================================================== CORRECTIONS AND NOTES ============================================================================== MORS_0101 AAREADME.TXT: Coverage dates in the format YYYY-MM-DD are one day thru too early. The YY/DDD dates are correct. MORS_0109 VOLDESC.CAT: The same is true for dates associated with the keyword VOLUME_NAME in the VOLDESC.CAT file. The AAREADME.TXT file and the VOLUME_NAME value were both corrected on MORS_0110. MORS_0101 CALINFO.TXT was omitted from the CALIB directory on all original thru volumes. It should be present on MORS_0156, Versions 4 and MORS_0156 later. DATA_SET_ID is "MGS-M-RSS-1-CRUISE-V1.0" in CATALOG/DATASET.CAT on all volumes except Versions 2 and later of MORS_0156. It should be "MGS-M-RSS-1-CRU-V1.0". RECORD_BYTES was 80 in all CATALOG/PERSON.CAT files; should be correctly set to 72 in Versions 2 and later of MORS_0156. There are scattered instances of non-standard ASCII characters in some text files. These were probably introduced by word processing software during compilation of the files. Non- standard characters include the TAB character, "smart" quotes, and non-standard hyphens. Expect these in: Many files in HEA directories Most labels in ODR directories Some files in the CATALOG directory Software Interface Specifications in the DOCUMENT directory Occasional label files in the SAK, SFO, and SOE do not have delimiters. DOCUMENT/TRK_2_24.TXT was omitted from all volumes; it is included in MORS_0156, Versions 2 and later. The first line in each daily health report (HEA/HEAydddC.TXT) has PDS_VERSION rather than PDS_VERSION_ID. This error was corrected with HEA/HEA8245A.TXT. With few, if any, exceptions, the values for MISSION_NAME and INSTRUMENT_HOST_NAME in labels for SAK files are "MARS_GLOBAL_SURVEYOR". This is an illegal value; double quotes or underscores are acceptable, but not both and not neither. MORS_0106 HEA/HEA6331A.TXT has no PDS label. MORS_0107 CUMINDEX.TAB and INDEX.TAB have some incorrect entries in the PRODUCT_CREATION_TIME column (column 7). These are short, so the records do not have the required 142 characters. MORS_0109 CALIB directory is missing; get CALIB files from MORS_0156, Versions 2 or later. MORS_0127 AAREADME.TXT: Added list of acronyms and abbreviations. Removed references to RSC11_11.TXT. INDEX/INDEX.LBL: DATA_SET_ID moved from object to label section. INDEX/CUMINDEX.LBL: DATA_SET_ID moved from object to label section. CATALOG: Editorial improvements to DATASET.CAT, INST.CAT, INSTHOST.CAT, MISSION.CAT, and REF.CAT. DOCUMENT/DOCINFO.TXT: Removed section on RSC11_11.TXT. Editorial corrections. DOCUMENT/MGSRSSIS.TXT: Editorial changes; now version 1.0.2. MORS_0128 HEA/HEA7092A.PS1 and HEA/HEA7093A.PS1 do not have PDS labels. MORS_0130 HEA/HEA7105B.PS1 does not have a PDS label. MORS_0131 This volume was originally prepared as though the data came from the Orbit Insertion phase of the mission rather than Cruise. Labels had incorrect DATA_SET_ID values; wrong AAREADME.TXT, ERRATA.TXT, and VOLDESC.CAT files were included; and the files in the INDEX directory were wrong. Ignore Version 1 of this CD; use Version 2 instead. Version 2 of MORS_0131 contains three extra files in the DOCUMENT directory: GDF_SPK.TXT, GDN_SPK.TXT, and OPTG_SIS.TXT. These are Software Interface Specifications written after the beginning of the Mars Orbit Insertion phase; they were accidently included when Version 2 was regenerated. OPTG_SIS.TXT might actually be useful with Cruise data; the other two SISs describe files that were not generated during the Cruise phase. MORS_0132 INDEX/CUMINDEX.TAB: Listings from MORS_0131 are missing. Get thru correct index for entire data set from MORS_0156, Versions MORS_0156 2 and later. MORS_0139 There is no label to accompany MCH/7142142A.MCH. If a label is needed, the label file MCH/7141141A.LBL could easily be copied and adapted by editing the FILE_NAME and PRODUCT_ID and advancing the day number in PRODUCT_CREATION_TIME, START_TIME, and STOP_TIME. MORS_0146 HEA/HEA7199A.PS1 does not have a PDS label. MORS_0150 All spacecraft CK files created since Launch are in the TCK directory on this CD. SFO/7214224A.LBL erroneously has PRODUCT_ID and FILE_NAME set to 7109140A.SFO; these should have been set to 7214224A.SFO. The corresponding entry in INDEX/INDEX.TAB and CUMINDEX.TAB was also incorrect (fixed on MORS_0156, versions 2 and later). SOE/7219225A.LBL erroneously has PRODUCT_ID and FILE_NAME set to 7217223A.SOE; these should have been set to 7219225A.SOE. The corresponding entry in INDEX/INDEX.TAB and CUMINDEX.TAB was also incorrect (fixed on MORS_0156, versions 2 and later). MORS_0152 HEA/HEA7227A.PS1 does not have a PDS label. MORS_0156 File 7145260A.SPK omitted from this volume; it appears on MORS_0201. File HEA7245A.TXT appears on both this volume and MORS_0201. Last volume in this volume set (MORS_0101 through MORS_0156) and data set (MGS-M-RSS-1-CRU-V1.0). Next volume (MORS_0201) picks up immediately as the first in data set MGS-M-RSS-1-MOI-V1.0. Version 2 of this volume contains a defective CATALOG/INST.CAT file in which double quotes (") meaning "inches" were erroneously embedded in text. This should have been corrected on Versions 3 and later. Version 2 of this volume contains a defective DOCUMENT/OPTG_SIS.TXT file in which the degree sysmbol was erroneously embedded in text. This should have been corrected on Versions 4 and later. The file was omitted entirely on Version 3. On Versions 3 and earlier the label file ECS/7125244A.LBL pointed to a file that did not exist. The pointer was corrected on Version 4, but the corresponding entry in INDEX/CUMINDEX.TAB was not updated until Version 5. On Versions 4 and earlier, AAREADME.TXT states that all files with the *.TXT extension have fixed length 80-character records. This is not true for *.TXT files in the ENB directory. AAREADME.TXT was corrected for Version 5. On Version 4 the TARGET.CAT file was added to the CATALOG directory. On Versions prior to 5, the contents of the DOCUMENT directory were incorrectly listed in DOCUMENT/DOCINFO.TXT.
