NAME


fitscheck - script to detect and fix FITS standards violations

SYNOPSIS


fitscheck [OPTION]... [FILE]...

DESCRIPTION


fitscheck is a command line script based on pyfits for verifying and updating the CHECKSUM
and DATASUM keywords of FITS files. itscheck can also detect and often fix other FITS
standards violations. fitscheck facilitates re-writing the non-standard checksums
originally generated by pyfits with standard checksums which will interoperate with
cfitsio.

fitscheck will refuse to write new checksums if the checksum keywords are missing or their
values are bad. Use --force to write new checksums regardless of whether or not they
currently exist or pass. Use --ignore-missing to tolerate missing checksum keywords
without comment.

OPTIONS


-h, --help
Display terse usage information (help).

-k [standard | nonstandard | either | none], --checksum=[standard | nonstandard | either |
none]
Choose FITS checksum mode or none. Defaults to standard.

-w, --write
Write out file checksums and/or FITS compliance fixes.

-f, --force
Do file update even if original checksum was bad.

-c, --compliance
Do FITS compliance checking, fix if possible.

-i, --ignore-missing
Ignore missing checksums.

-v, --verbose
Generate extra output.
