Infrared Astronomical Satellite, IRAS
Working Survey Database and Ancillary Files
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.
