wcstools - Programs to access image world coordinate systems and catalogs
Setting an Image World Coordinate System
imwcs Automatically find stars in a FITS or IRAF image, match them to HST Guide USNO A or USNO UJ Stars,
compute the relation between sky coordinates and image coordinates, and write in in the image
header. [after U of Iowa SETWCS]
delwcs Delete the WCS keywords from an image. If both EPOCH and EQUINOX are present, EQUINOX is also
deleted.
Using an Image World Coordinate System
imcat List catalog sources which should be found in the area of the sky covered by a specific image.
imsize Print center and size of image using WCS keywords in header
imstar Find and list the n brightest stars in an IRAF or FITS image, with their sky coordinates if there
is WCS information in the image header.
sky2xy Print image pixel coordinates for given sky coordinates on the command line or in a list file.
xy2sky Print sky coordinates for given image pixel coordinates on the command line or in a list file.
Catalog Utility Programs
scat Search the HST GSC, USNO-A2.0, or other catalog given a region on the sky.
skycoor
Convert between J2000, B1950, and Galactic coordinates from the command line or a file.
