Synopsis¶

imua2 [options] FITS or IRAF file(s)

Description¶

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.

Options¶

-b [<RA> <Dec>]

Output in B1950, optional new image center in B1950 (FK4) RA and Dec

-h

Print heading, else do not

-j [<RA> <Dec>]

Output in J2000, optional new image center in J2000 (FK5) RA and Dec

-m [<bright magnitude>] <faint magnitude>

Limiting catalog magnitude(s) (default none, bright -2 if only faint is given)

-n <num>

Number of brightest stars to print

-p <scale>

Initial plate scale in arcsec per pixel (default 0)

-s

Sort by RA instead of flux

-t

Tab table to standard output as well as file

-u

USNO catalog single plate number to accept

-v

Verbose listing of processing intermediate results

-w

Write tab table output file imagename.cat -z Use AIPS classic projections instead of WCSLIB; use CD matrix or CDELT instead of polynomial solution.
