Program FixFITS This program is designed to correct a common error in FITS files in which the initial "SIMPLE = ... T" is not in the prescribed form. This operation is done by making a copy of the input file with the correction added to the output file. The program checks to see if the initial characters are "SIMPLE " and if so inserts the correct string. FixFITS is run from DOS with two arguments, the input, illegal FITS file and the output file e.g. FIXFITS badFITS.FIT OKFITS.FIT
