[fitsbits] Start of the CHECKSUM Public Comment Period
This is to announce the start of the 30-day Public Comment Period on the
CHECKSUM FITS keyword convention that has been submitted for inclusion in the 'Registry of FITS Conventions' which is maintained by the IAU FITS Working Group. This is the 7th in a growing series of conventions submitted for inclusion in the Registry. A document describing this convention and a sample FITS file that uses it are available for public review and comment from the FITS registry web page at http://fits.gsfc.nasa.gov/fits_registry.html Under this convention, the CHECKSUM and DATASUM header keywords are used to verify the integrity of the HDU. Verifying that the accumulated 32-bit 1's complement checksum of the HDU is equal to -0 provides a fast and fairly reliable way to determine that the HDU has not been modified or corrupted. Comments may be posted here on the FITSBITS mail exploder or the sci.astro.fits newsgroup. Minor typographical issues may be sent directly to the authors of the convention.
