Simpson Stanford University ============================================================================== INTRODUCTION ============================================================================== This file contains an accumulation of corrections and notes for the 'Voyager 1: Raw Radio Science Data from Saturn - Egress' data set. ============================================================================== CORRECTIONS AND NOTES ============================================================================== VG_2311 Version 2 of these volumes corrected some minor errors in format thru and content. VG_2316 VG_2317 Version 1: In VOLDESC.CAT the value of VOLUMES is set to "28". The thru double quotes around the number should be removed. Corrected in VG_2338 Version 2. Version 1: GEOMETRY/GEOMINFO.TXT says CRS009AA.CRS is included in the GEOMETRY directory. CRS009AA.CRS is the CRS file for the Voyager 1 encounter with Titan; it is CRS010AA.CRS that is included in this archive. Corrected in Version 2. The following notes apply to all versions of the volumes: VG_2311 BODIES_TABLE in GEOMETRY/CRS010AA.CRS is filled with values equal thru to 0. Although one might have hoped for better, this is how the VG_2338 file was provided to science teams by the Voyager Project. The binary file GEOMETRY/VH014.DAT has 3322 records, but its ASCII counterpart GEOMETRY/VH014T.TAB has only 3321. Software which made the binary to ASCII conversion did not convert the final binary record. Users of Adobe Illustrator may encounter problems displaying files in the BROWSE directory. Cause of the problem is not known, but it appears to be connected with the manner in which the four original figures were combined into a single PostScript file. By hand editing the four-panel PostScript files, one user was able to extract the individual figures and successfully display those using Illustrator. Other methods of looking at the BROWSE files (such as ghostview or sending the files to a PostScript printer) have worked successfully for a number of other users. Labels for files in the BROWSE directory state that the lower right panel is an extract of the first few lines of the source ODR PDS label. In fact, it is the complete ODR PDS label. VG_2312 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6217AA.ODR and ODR/VJ6252AA.ODR. VG_2313 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6227AA.ODR and ODR/VJ6260AA.ODR. VG_2314 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6269AA.ODR. VG_2315 Starting at about 04:31 on VJ6278AA.ODR and continuing through the end of VJ6280AA.ODR the input voltage to the analog-to- digital converters on the X-LCP channel was set too high, and the data should be considered lost. Little or no signal was expected in this channel, however, so the impact on science should be minimal. Two of the three corresponding tapes from Recorder B (VJ6164 and VJ6166) are missing and presumed lost. VG_2316 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6028AA.ODR, ODR/VJ6029AA.ODR, ODR/VJ6056AA.ODR and ODR/VJ6057AA.ODR. VG_2317 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6030AA.ODR, ODR/VJ6031AA.ODR, ODR/VJ6032AA.ODR, ODR/VJ6033AA.ODR, ODR/VJ6034AA.ODR, and ODR/VJ6068AA.ODR. VG_2318 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6038AA.ODR. VG_2319 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6009AA.ODR. VG_2319 At least one record was lost due to deterioration of the original VJ6082 magnetic tape. ODR/VJ6082AA.ODR and ODR/VJ6082BB.ODR are the two file 'fragments' of good data that were recovered. VJ6082AA.ODR contains about 1 second of data; VJ6082BB.ODR contains about 100 seconds. PREPPOWER plot was not generated in BROWSE/VJ6009AA.PS. PREPPOWER and PREPLOOK plots were not generated in BROWSE/VJ6082AA.PS because there is not enough data in the ODR. VG_2322 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6398AA.ODR and ODR/VJ6420AA.ODR. PREPPOWER plot was not generated in BROWSE/VJ6397AA.PS. VG_2323 At least one record was lost due to deterioration of the original VJ6428 magnetic tape. ODR/VJ6428AA.ODR and ODR/VJ6428BB.ODR are the two file 'fragments' of good data that were recovered. VJ6428AA.ODR contains about 88 seconds of data; VJ6428BB.ODR contains about 10 seconds. VG_2326 PREPPOWER plot was not generated in BROWSE/VJ6473AA.PS. Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6508AA.ODR. VG_2327 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6102AA.ODR. VG_2328 PREPPOWER plot was not generated in BROWSE/VJ6104AA.PS or BROWSE/VJ6105AA.PS. VG_2329 VJ6164AA.ODR was not included in the ODR directory because the file could not be found when the archive was created. Users may find equivalent data in VJ6278AA.ODR on VG_2315, but part of this file was corrupted. VJ6166AA.ODR was not included in the ODR directory (after the first version of the CD) because the file could not be found. On version 1 of the CD, data from VJ6169 had been erroneously substituted. Corresponding data from Recorder A are corrupted, so this segment of the experiment must be considered lost. VG_2332 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6537AA.ODR. VG_2333 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6533AA.ODR and ODR/VJ6547AA.ODR. PREPPOWER plot was not generated in BROWSE/VJ6513AA.PS. VG_2334 One record was lost due to deterioration of the original VJ6565 magnetic tape. ODR/VJ6565AA.ODR and ODR/VJ6565BB.ODR are the two file 'fragments' of good data that were recovered. VJ6565AA.ODR contains 5179 records of data; VJ6565BB.ODR contains 820 records. The first good time tag in VJ6565BB.ODR is in record 41. VG_2335 Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6558AA.ODR. VG_2336 VJ6642AA.ODR was not included in the ODR directory (after the first version of the CD) because the file could not be found. On version 1 of the CD, data from VJ6647 had been erroneously substituted. There are no corresponding data from Recorder B, so this segment of the calibrations must be considered lost. VG_2337 PREPPOWER plot was not generated in BROWSE/VJ6616AA.PS. Spacecraft ID was unexpectedly found to be 95 in (at least) the first two records of ODR/VJ6616AA.ODR, ODR/VJ6629AA.ODR, and ODR/VJ6644AA.ODR. VG_2338 There is no INDEX/INDEX.TAB file on this volume because there are no data files (file types ODR or BROWSE). This volume contains ancillary files and the complete document collection for the data set.
