delwcs (pronounced del-W-C-S) is a utility for removing world
coordinate system information from the header of a FITS or IRAF image.
World coordinate system (WCS) information in the image header describes,
in a standard way, the relationship between sky coordinates and image pixels.
This information is used by the program to transform image right ascension
and declination sky coordinate pairs to image coordinate (X,Y) pairs.
The keywords CTYPE1, CRVAL1, CDELT1, CRPIX1,
CROTA1, CTYPE2, CRVAL2. CDELT2, CRPIX2,
and CROTA2 are deleted from the image header.
If both EQUINOX and EPOCH keywords are present, EQUINOX
is removed as well.
Command Line Arguments
filename
Name of FITS or IRAF image file. This must be present.
-v
print more information about process
-n
Write output to a new file with an "e" before the file type extension:
x.fits becomes xe.fits.
