- Automaticaly 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.
