Find USNO UJ1.0 Stars in Image Region

WCSTools programs
imujc is a link to the WCSTools imcat utility which finds all of the U.S. Naval Observatory UJ Catalog objects in a FITS or IRAF image and lists their sky and image positions. World coordinate system (WCS) information must be present in the image header to describe, in a standard way, the relationship between sky coordinates and image pixels. This information is used by the program to find the region in the sky to search and to transform right ascension and declination sky coordinate pairs to image coordinate (X,Y) pairs. Output is sent to a file called filename.ujc and to standard output if the -v flag is set. The UJ number is the zone ((90 + declination in degrees) * 10) followed by the sequence number of the star within the RA-sorted zone.
