It serves only as a minimal description of the general format COMMENT and structure of the data file. A copy of "Faint Source Survey COMMENT Explanatory Supplement", Version 2, should be used to answer COMMENT questions about the data in the IRAS Faint Source Catalog. COMMENT Source Catalog Reference: IRAS Faint Source Catalog, Version 2.0, COMMENT IPAC, 1990 September. COMMENT This table contains only the point source association fields for each COMMENT source in the IRAS FSC. The observational data for each source are COMMENT in table FSC_Data. Each association is tagged with the IRAS source name COMMENT with which it is associated, as well as the sequential record number COMMENT within table FSC_Data where the observational data can be found. COMMENT Field names are identical with the field names given in COMMENT the IRAS Faint Source Survey Explanatory Supplement.

Values of 9999 COMMENT indicate the field has saturated. For some catalogs Field3 COMMENT contains 0 when there is no information instead of -999. Read COMMENT the supplement (referenced above) to learn which catalogs put a COMMENT value in each of the fields.
