sujc
USNO UJ1.0 Catalog Search Program

WCSTools programs
sujc is a utility for finding objects in the U.S. Naval Observatory UJ Catalog within a specified region of the sky and listing their sky positions. It is a symbolic link to scat, and is equivalent to running scat -c ujc ....

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.gsc or search.gsc. It is somewhat similar to RGSC, which can search from lists of coordinates but cannot sort the output. The UJ number is the zone ((90 + declination in degrees) * 10) followed by the sequence number of the star within the RA-sorted zone.

Command Line Arguments

Examples
