- The Machine Readable Version of the Point Source Catalog
-
- The point source catalog tape is divided into six individual
- files, covering the range 0 to 24 hr in right ascension in blocks
- of four hours each. Files are named IRASnnnn, where nnnn is
- the right ascention range for the file, thus IRAS0408 contains
- entries between 4 and 8 degrees. Each file contains from 20,000
- to 90,000 sources arranged in order of increasing right
- ascension.
-
- Association information requires an additional 40 characters per
- association and appears in subsequent records, two associations
- per record. If one assumes an average of two associations per
- source, then a file for one of the right ascension blocks will
- require about 10 Mbytes.
