Program Descriptions
addpix Add a constant value(s) to specified pixel(s)
conpix Operate on all of the pixels of an image
cphead Copy keyword values between FITS or IRAF images
delhead Delete specified keywords from FITS or IRAF image file headers
delwcs Delete the WCS keywords from an image. If both EPOCH and EQUINOX are present, EQUINOX is also deleted.
edhead Edit the header of a FITS file or the user parameters of an IRAF image file using a the text editor specified by the EDITOR environment variable.
getcol Extract specified fields from an space-separated ASCII table file
getdate Convert dates and times between various formats
gethead Return values for keyword(s) specified after filename.
getpix Return value(s) of specified pixel(s)
gettab Extract values from tab table data base files
i2f Read two-dimensional IRAF image file and write FITS image file
imcat List catalog sources which should be found in the area of the sky covered by a specific image. Special catalogs supported include the HST Guide Star Catalog, the USNO-A2.0 Catalog, the Tycho-2 Catalog, the SAO Catalog, and the PPM Catalog.
imextract Extract 1- or 2-dimensional images from 2- or 3-dimensional images
imhead Print FITS or IRAF header
immatch Match catalog and image stars using the WCS in the image file.
imrot Rotate and/or reflect FITS or IRAF image files
imsize Print center and size of image using WCS keywords in header imcat List catalog sources which should be found in the area of the sky covered by a specific image. Special catalogs supported include the HST Guide Star Catalog, the USNO-A2.0 Catalog, the Tycho-2 Catalog, the SAO Catalog, and the PPM Catalog.
imextract Extract 1- or 2-dimensional images from 2- or 3-dimensional images
imhead Print FITS or IRAF header
immatch Match catalog and image stars using the WCS in the image file.
imrot Rotate and/or reflect FITS or IRAF image files
imsize Print center and size of image using WCS keywords in header
imstack Stack 1-dimensional images into a 2-dimensional image
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.
imwcs Automaticaly find stars in a FITS or IRAF image, match them to HST Guide or UJC Stars, compute the relation between sky coordinates and image coordinates, and write in in the image header.
keyhead Change keyword names in headers of FITS or IRAF images.
newhead Create dataless FITS image header files with BITPIX=0
remap Remap an image from one WCS into another, rebinning as necessary
sethead Set header keyword values in FITS or IRAF images.
setpix Set specified pixel(s) to specified value(s)
scat Search a source catalog given a region on the sky. Special catalogs supported include the HST Guide Star Catalog, the USNO A and ACT Catalogs, the SAO Catalog, and the PPM Catalog.
sky2xy Print image pixel coordinates for given sky coordinates on the command line or in a list file.
skycoor Convert between J2000, B1950, and Galactic coordinates from the command line or a file.
sumpix Total pixel values over an image row or column or a specified area
wcshead Print basic world coordinate system information on one line per image
xy2sky Print sky coordinates for given image pixel coordinates on the command line or in a list file.
