Catalog Files

Catalog files contain the overview information and parameters used in loading the PDS central catalog, specifically, or for developing other interfaces to the data outside of PDS. The information they contain, particularly in their descriptive text fields, should be clear, complete, and understandable to a research user who is not necessarily a mission or instrument specialist.

These files are located in the catalog/ subdirectory. The directory contents are described by the catinfo.txt file.

• Support Archives Mission Catalog File
• McDonald 2.7m Instrument Host Catalog File
• IDS Instrument Catalog File
• LCS Instrument Catalog File
• Data Set Catalog File
• 19P/Borrelly 1 Target Catalog File

Data Files

The data are divided into three files. Each is an ASCII table with a separate PDS label:

• Image Dissector Scanner (IDS) Observations, (PDS label)
• Large Cassegrain Spectrograph (LCS) observations (PDS label)
• Table of observational parameters for both IDS and LCS observations (PDS label)
