Default [fitsbits] Start of "Tiled Image Compression" Public Comment Period

This is to announce the start of the 30-day public comment period on the
"Tiled Image Compression" FITS convention that has been submitted for
inclusion in the "Registry of FITS Conventions" that is maintained by the
IAU FITS Working Group.

A document describing this convention, and some sample FITS files that
illustrate its usage are available for public review and comment from the
FITS registry web page at

http://fits.gsfc.nasa.gov/fits_registry.html

Here is a brief description:

This is a convention for compressing FITS images and storing the compressed
byte stream in a variable-length array column in a FITS binary table.
Optionally, the image may be divided into rectangular tiles, and each tile
is compressed separately. Any number of different compression algorithms can
be supported. Current implementations support GZIP, RICE, H-Compress, and
the IRAF pixel list compression algorithms.

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.

Bill Pence
(on behalf of the IAU FITS Working Group)
