WCSTools
Programs
which use the
USNO A-1.0,
A-2.0,
and
SA-1.0,
SA-2.0
Catalogs
These programs are part of the WCSTools software
package, a self-contained package of programs and libraries for accessing
catalogs and images and using them together in interesting ways. It is
written in very portable C code, and sources are available
here.
Catalog Search Programs
- sua1
- Search the U.S. Naval Observatory A-1.0 Catalog (UA1) given a search center and
a radius, with optional magnitude limits. (link to
scat)
- sua2
- Search the U.S. Naval Observatory A-2.0 Catalog (UA2) given a search center and
a radius, with optional magnitude limits. (link to
scat)
- susa1
- Search the U.S. Naval Observatory SA-1.0 Catalog (UAC) given a search center and
a radius, with optional magnitude limits. (link to
scat)
- susa2
- Search the U.S. Naval Observatory SA-2.0 Catalog (UAC) given a search center and
a radius, with optional magnitude limits. (link to
scat)
- scat
- Search the GSC, USAC, UAC, UJC, or a local catalog given a search center
and a radius, with optional magnitude limits.
Using an Image World Coordinate System
- imua1
- Find and list the USNO A-1.0 Catalog Stars in an IRAF or FITS image, with
their pixel coordinates, if there is WCS information in the image header.

- imua2
- Find and list the USNO A-2.0 Catalog Stars in an IRAF or FITS image, with
their pixel coordinates, if there is WCS information in the image header.

- imusa1
- Find and list the USNO SA-1.0 Catalog Stars in an IRAF or FITS image, with
their pixel coordinates, if there is WCS information in the image header.
(link to imcat)
- imusa2
- Find and list the USNO SA-2.0 Catalog Stars in an IRAF or FITS image, with
their pixel coordinates, if there is WCS information in the image header.
(link to imcat)
- imcat
- Find and list the HST Guide Star Catalog, the USNO A Catalogs, the
USNO SA Catalogs, USNO UJ Catalog, or user-catalogued stars in an IRAF
or FITS image, with their pixel coordinates if there is WCS information
in the image header.
Setting an Image World Coordinate System
- imwcs
- Automatically find stars in a FITS or IRAF image, match them to HST
Guide Stars, USNO A Catalog stars, USNO SA Catalog stars, USNO UJ
Catalog stars, or a locally-assembled reference catalog, compute the
relation between sky coordinates and image coordinates, and write the
resulting world coordinate system keywords into the header of a copy
of the original image.
- immatch
- Automatically find stars in a FITS or IRAF image and match them to HST
Guide Stars, USNO A Catalog stars, USNO SA Catalog stars, USNO UJ
Catalog stars, or a locally-assembled reference catalog based on the
relation between sky coordinates and image coordinates given by the
world coordinate system keywords in the header of the image.
