siras
Search the IRAS Point Source Catalog (IRAS)

WCSTools programs
siras finds objects in the IRAS Point Source Catalog within a specified region of the sky and lists their sky positions or lists specific entries in that catalog. It is a symbolic link to scat, and is equivalent to running scat -c iras ....

By default, only the brightest 100 objects (or closest 100, if the -p option is used) are returned. Use the -n option to increase this number.

Output is to standard out, unless the -w flag is set, in which case it goes to objectname.iras or search.iras. It is a link to scat and is somewhat similar to riras, which can search from lists of coordinates but cannot sort the output. This program automatically senses the byte order of the catalog and, if necessary, swaps it to match the byte order of the machine on which it is executing.

Set the environment variable WCS_BINDIR to the directory containing the file IRAS for searching and for access by number.
