PROGRAM:
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.
OPTIONS
-s statusfile
Output and errors are sent to statusfile instead of to stdout
ARGUMENTS
img.fits
Path of FITS file to be validated.
