imua2 - Find USNO-A2.0 stars in FITS or IRAF image files

imua2 [options] FITS or IRAF file(s)

Search USNO-A2.0 Catalog within the area described by the world coordinate system in an image header. This is a link to imcat rather than a separate executable.

Output in B1950, optional new image center in B1950 (FK4) RA and Dec
Print heading, else do not
Output in J2000, optional new image center in J2000 (FK5) RA and Dec
Limiting catalog magnitude(s) (default none, bright -2 if only faint is given)
Number of brightest stars to print
Initial plate scale in arcsec per pixel (default 0)
Sort by RA instead of flux
Tab table to standard output as well as file
USNO catalog single plate number to accept
Verbose listing of processing intermediate results
Write tab table output file imagename.cat -z Use AIPS classic projections instead of WCSLIB; use CD matrix or CDELT instead of polynomial solution.
