NAME


mHdrCheck - Check the validity of a FITS image's header

SYNOPSIS


mHdrCheck [-s statusfile] img.fits

DESCRIPTION


mHdrCheck reads in the header from a FITS image (or an ASCII header template file) and
checks to see if any header lines are invalid. If it finds one, it will print out a
message stating which keyword is invalid and exit before checking the rest of the header.
It will not report on multiple invalid values. If all value are correct, mHdrCheck will
print out a "Valid FITS/WCS" message.
