[fitswcs] [Fwd: Start of the HEALPix "Public Comment Period"]

[William Pence]

The following message, posted to the FITSBIT mail list today, may be of 
interest to readers of this fitswcs mail list:

-------- Original Message --------

This is to announce the start of the 4-week formal Public Comment Period on
the paper "Mapping on the HEALPix grid" by Mark Calabretta and Boud Roukema.
  A link to the latest version of the paper is available at
http://www.atnf.csiro.au/~mcalabre/WCS.  Particular attention should be
given to section 6 of this paper which presents the HEALPix spherical
projection in the same terms as the other projections presented in the FITS
WCS Paper II on the "Representations of celestial coordinates in FITS"
(which is also available from that web site).  The authors of this paper
have requested that the IAU FITS Working Group consider approving section 6
as an extension of the FITS WCS standard.

All interested members of the FITS community are urged to submit comments
about this proposal here on the sci.astro.fits newsgroup, or on the related
FITSBITS moderated mail list.  Following the conclusion of this formal
comment period, it is likely that the 4 regional FITS committees and the IAU
FITS Working Group will then vote on whether to formally adopt this proposal.


William Pence
Chairman, IAU FITS Working Group
