This is to announce the official start of the 4-week formal Public Comment

Greisen, Mark Calabretta, Frank Valdes, and Steve Allen. This Public
Comment Period is the first step in the process of approving this paper as
part of the official FITS Standard.

This important paper describes detailed conventions for defining spectral
coordinates involving wavelength, frequency, and velocity in FITS files.

Background information on the FITS approval process

Under the "Rules and Procedures" of the IAU FITS Working Group, the first
step in the official approval process of any FITS proposal will be a formal
Public Comment Period to take place on the sci.astro.fits newsgroup
(and on the moderated FITSBITS mail list that mirrors all on-topic
postings). At the end of this public comment period the regional FITS
committees (North America, Europe, Japan, and Australia/New Zealand) will
then vote on the proposal. Following that the IAU FITS Working Group will
then conduct a final vote to approve or disapprove the proposal. These
rules and procedures are more fully described at
