Table 1 lists the entries in each WSDB file, their variable types and lengths. Most of the information in the Ancillary file is the same as that in the Point Source Catalog .
All arithmetic quantities are in integer format with the high order byte first.
12 ELAT Ecliptic latitude 1950. The threshold was purposefully set quite low so that sources with weak continua but strong lines could be detected. The positions and predicted brightnesses of some 32,000 point sources including SAO stars, IRC objects and asteroids were incorporated into the data reduction software to provide a check on the positional and photometric accuracy of the IRAS sources. Table 3 lists the range of KSID values assigned to sources of various types. Note that an instrumental flux, not the flux density, is given.
