END ____________________________________________________________________________ Ida/Gaspra Special Collection PDS Small Bodies Node December 1999. This CDROM contains observations of the asteroids (243) Ida and (951) Gaspra extracted from the holdings of the Small Bodies Node, combined with observations by the Galileo mission magnetometer and solid state imaging system. Distinct DATA_SET_ID values have been assigned to these files to differentiate them from the full data sets from which they were extracted. A DATA_SET_COLLECTION description has been provided to easily identify this collection in the PDS central catalog. Existing PDS catalog files (for the Galileo mission and instruments and the SBN asteroid catalogs) are duplicated here for the convenient reference of the user. Some additional documentation and indexing are also provided. [NOTE: The TARGET catalog files for targets (other than Ida and Gaspra) mentioned in the Galileo mission description are NOT included here. These are available from the PDS Central Node.] The collection was reviewed in October 1995 and has since been residing in the on-line archives of the Small Bodies Node, available to users. This disk is being created now to formally ingest the collection into the PDS archives. Note that the original collection included preliminary listings for the Galileo Near-Infrared Mapping Spectrometer (NIMS) Experiment Data Record (EDR) files. However, interpretation of these files is a complex affair - so much so that they are not being included in this collection. Users interested in the NIMS data should inquire directly of that science team. As of this writing, the NIMS team maintained a Web site at this URL: http://jumpy.igpp.ucla.edu/~nims/ The medium and supporting files required for review were prepared by: Carol Neese Small Bodies Node, Planetary Data System Planetary Science Institute 620 North 6th Ave. Tucson, Arizona 85705-8331 Subsequent format editing and preparation of additional documentation required for final archiving were performed by personnel of the Small Bodies Node at the University of Maryland. For further information about the contributing catalogs, please consult the PDS catalog files specific to each dataset, located in the /catalog subdirectory. The data are in subdirectories of the /data directory: Directory Contents --------- -------- data/galileo_mag Galileo magnetometer observations data/galileo_ssi Galileo solid state imaging system observations data/lightcurves Lightcurves from the Asteroid Photometric Catalog data/spectra Spectra (and colors) from several survey catalogs The following DATA_SET_IDs are included in this delivery: DATA_SET_ID Contents ----------- -------- EAR-A-3-EDC-IDA/GASPRA-APC/LC-V1.0 Published lightcurves EAR-A-3-EDC-IDA/GASPRA-SPECTRA-V1.0 Published spectra and colors GO-A-SSI-2-REDR-IDA/GASPRA-V1.0 Galileo SSI Images GO-A-MAG/POS-3-RDR/SUMM/TRAJ-IDA-V1.0 Galileo magnetometer - Ida GO-A-MAG/POS-3-RDR/SUMM/TRAJ-GASPRA-V1.0 Galileo magnetometer - Gaspra Note that the magnetometer data sets also include a file of trajectory data relevant to the recorded observations. ============================================================================= Anne Raugh, 13 June 2001 - DATA_SET_IDs changed for ingest
