Setting an Image World Coordinate System

10       imwcs  Automatically find stars in a FITS or IRAF image, match them  to
11              HST  Guide  USNO A, B, UCAC or UJ Stars,  or others, compute the
12              relation between sky  coordinates  and  image  coordinates,  and
13              write in in the image header. [after U of Iowa SETWCS]
14
15       delwcs Delete the WCS keywords from an image. If both EPOCH and EQUINOX
16              are present, EQUINOX is also deleted.
17

Using an Image World Coordinate System

19       imcat  List catalog sources which should be found in the  area  of  the
20              sky covered by a specific image.
21
22       imsize Print center and size of image using WCS keywords in header
23
24       imstar Find  and  list  the n brightest stars in an IRAF or FITS image,
25              with their sky coordinates if there is WCS  information  in  the
26              image header.
27
28       sky2xy Print  image  pixel coordinates for given sky coordinates on the
29              command line or in a list file.
30
31       xy2sky Print sky coordinates for given image pixel coordinates  on  the
32              command line or in a list file.
33

Catalog Utility Programs

35       scat   Search  the  HST GSC, USNO-A2.0, or other catalog given a region
36              on the sky.
37
38
39       skycoor
40              Convert between J2000, B1950,  and  Galactic  coordinates
41              from the command line or a file.
42

53       getpix Return value(s) of specified pixel(s)
54
55       i2f    Read two-dimensional IRAF image file and write FITS image
56              file
57
58       imhead Print FITS or IRAF header
59
60       imrot  Rotate and/or reflect FITS or IRAF image files
61
62       setpix Set specified pixel(s) to specified value(s)
63
64       sethead
65              Set header parameters in FITS or IRAF images.
