HR-edZddlZddlZddlZddlZddlmZddlmZej dZ d Z dZ dZd Zd Zd Zd Zdd ZdS)a ``fitscheck`` is a command line script based on astropy.io.fits for verifying and updating the CHECKSUM and DATASUM keywords of .fits files. ``fitscheck`` can also detect and often fix other FITS standards violations. ``fitscheck`` facilitates re-writing the non-standard checksums originally generated by astropy.io.fits 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. Example uses of fitscheck: 1. Add checksums:: $ fitscheck --write *.fits 2. Write new checksums, even if existing checksums are bad or missing:: $ fitscheck --write --force *.fits 3. Verify standard checksums and FITS compliance without changing the files:: $ fitscheck --compliance *.fits 4. Only check and fix compliance problems, ignoring checksums:: $ fitscheck --checksum none --compliance --write *.fits 5. Verify standard interoperable checksums:: $ fitscheck *.fits 6. Delete checksum keywords:: $ fitscheck --checksum remove --write *.fits N) __version__)fits fitscheckag e.g. fitscheck example.fits Verifies and optionally re-writes the CHECKSUM and DATASUM keywords for a .fits file. Optionally detects and fixes FITS standard compliance problems. This script is part of the Astropy package.
