wcshead - Print WCS part of FITS or IRAF image header
Synopsis
wcshead [-hrtvsz] FITS or IRAF file(s)
Description
wcshead is a utility for printing the world coordinate system information in IRAF and FITS image headers. It converts IRAF .imh image head-
ers to FITS format before extracting the information. For IRAF files, the image dimensions and the object name are set from the binary
portion of the header.
Options-h Print CRVALs as hh:mm:ss and dd:mm:ss instead of degrees
-r Print first dimension as rest wavelength limiting values
-t Print tab-separated table output, with headers
-v Print more intermediate information for debugging
-w Print only first dimension limiting values (wavelength for spectra)
-z Use AIPS classic projections instead of WCSLIB

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