The WSDB and its Ancillary Files give a detailed description of the
observational and data processing history of each IRAS point source.
These files are meant to give the sophisticated researcher all the
available data on any given source, such as its brightness on each
hours-confirmed sighting, the detectors involved, and the details of
the data reduction (e.g., confusion with neighboring sources). The
WSDB is in binary format and is broken up into 20 files, one for each
range of ecliptic longitudes called a survey
Lune. The Ancillary Files contain
flags and derived quantities obtained during final generation of the
IRAS Point Source Catalog. Like the WSDB, the
Ancillary Files are in binary format and subdivided into Lunes.
