Connerney jec@lepjec.gsfc.nasa.gov NASA Goddard Space Flight Center Code 695 Greenbelt, MD 20771 An updated version of this file is maintained online at the Planetary Plasma Interactions Node of the Planetary Data System. The online errata list can be found on the World Wide Web at http://www.igpp.ucla.edu/ssc/pdsppi/Welcome.html. The list also can be obtained via anonymous FTP at ftp.igpp.ucla.edu. The user name is "anonymous" and the password should be your e-mail address (it's polite to leave an audit trail). Locate yourself in the PDS errata directory (cd pds/ERRATA/MGSM_2xxx), and transfer the file ERRATA.TXT (get ERRATA.TXT). Cumulative errata for the MGSM_xxxx volume set: Logical Volume Error/Variance Description ------------------------------------------------------------------------- MGSM_1xxx The files in the DOCUMENT directory contain a draft copy of and the VOLSIS document. The text version of the document MGSM_2xxx (VOLSIS.ASC), which is included for completeness, is not optimally formatted; in particular, the tables are not displayed properly and the illustrations are not displayed. Please refer to the other versions of the document (VOLSIS.HTM, VOLSIS.DOC) for the tables and illustrations. The headers of *.STS files may contain null characters (ASCII 0). Some software will display these non-printing characters as small squares. Other software may open these files in binary or hexadecimal format. The URL for the PPI Errata web page was not yet finalized at the time of the current release of this disk. Hence the URL of the PPI home page was given instead. (This URL is found in files AAREADME.TXT and ERRATA.TXT, and as links in AAREADME.HTM.) The PostScript files under the BROWSE directory have been labeled as documents. However, since they contain only image data, they do not have separate ASCII versions. Also, these files have PDS labels which point to multiple files from a single label. Although this kind of multiple labeling is permitted by the PDS Standards, some PDS software may handle such labels incorrectly. During the peer review of these disks, the possibility of adding an ASCII drawing of the ER mounting to the file ER_INST.CAT was discussed. This proved to be impractical due to the need to rotate existing ASCII drawings of the spacecraft (in CATALOG/MAG_INST.CAT and GEOMETRY/MAG_ER.TI) by angles other than 90 degrees while maintaining the clarity of the drawings. Hence two illustrations of the ER geometry, both in JPEG format, were added to the GEOMETRY directory of this disk. Please refer to those figures, and to CATALOG/ER_INST.CAT, CATALOG/MAG_INST.CAT and GEOMETRY/MAG_ER.TI, for information on the positioning of the ER instrument and on the geometry of the spacecraft in general. The PDS has clarified its standards regarding index files on PDS data volumes. As a result, all new MGSM_1xxx volumes will contain both an INDEX.TAB file and a MANIFEST.TAB file in the INDEX directory. The INDEX.TAB file will list only detached data label files and any data files with attached PDS labels. It represents a standard PDS index file. The MANIFEST.TAB file will be a complete index of all files on the disk. There also will be corresponding cumulative index and manifest files. The files /CATALOG/REF.CAT and /DOCUMENT/DOCINFO.TXT, which contain literature references, have been updated a number of times during the evolution of these disks. Hence these files will be more up-to-date and comprehensive on later volumes. The catalog files (/CATALOG/*.CAT) may be updated during the evolution of these disks. Hence these files may be more up-to-date on later volumes. MGSM_1001 Limited data are available for DOY 086, 106, 116, 117 and 119. MGSM_1002 The ORBFACTS.TAB file in the GEOMETRY directory does not cover the day of the earliest data on the disk (DOY 147). For DOY 148, 149 and 150, MAG data exist but could not be processed due to a lack of ancillary data. Hence these days of MAG data are not included on the disk. MGSM_1006 Limited data are available for DOY 260. No data are available for DOY 257 - 259 and 261 - 265. MGSM_1007 The ORBFACTS.TAB file in the GEOMETRY directory provides through orbit periapsis and apoapsis information referenced to Mars MGSM_1010 rather than to Phobos. This file does not cover the day of the earliest data on disk MGSM_1007 (DOY 147). MGSM_2001 The ORBFACTS.TAB file in the GEOMETRY directory does not cover the day of the earliest data on the disk (DOY 067). MGSM_2001 On these volumes, the VOLDESC.CAT file does not have the through LOGICAL_VOLUME_PATH_NAME keyword that the PDS standards MGSM_2008 require it to have. This is because the decision to treat these volumes as PDS logical volumes was not made until after the volumes were completed. After the production of these logical volumes, updated versions of the files MISSION.CAT and ER_DS.CAT in the CATALOG directory became available. These updated files (or further updates of them) will be placed on later disks in the DVD series. The file DATA/ANCIL/PCK.LBL contains two occurrences of the value PCK for the KERNEL_TYPE keyword. The correct standard value is TARGET_CONSTANTS. In the files FIG1.LBL and FIG2.LBL in the DOCUMENT directory, the keyword ENCODING_TYPE has the value GIF89. The correct standard value is GIF89A. In the VOLDESC.CAT file, the VOLUME_NAME keyword value contains the word "PREMAPPING". The correct word is "MAPPING". Personnel listed in the /CATALOG/PERSON.CAT file as having a PDS_USER_ID value of "N/A" actually do have PDS_USER_IDs. The value, in these instances, should be composed from the person's first initial and last name (for example, the ID for John Doe would be JDOE). In *.LBL files in directory /DATA/ER, the MISSION_PHASE keyword should have the value "MAPPING", not "ORBIT_INSERTION". MGSM_2002 There are no data and no HGA kernels available for DOY 087. There are very little MAG data and no ER data available for DOY 088. There are no data available for DOY 089 - 091 (these are around the time of the HGA deployment). MGSM_2004 There are some data available, but no HGA kernels available, for DOY 106. There are no data available for DOY 107 - 118 (these are around the time that the spacecraft was in contingency mode). MGSM_2005 Limited data are available for DOY 126, because of missing HGA kernels.
