[fitsbits] HPX projection
Greetings, A new draft of "Mapping on the HEALPix grid" by Calabretta & Roukema is available from http://www.atnf.csiro.au/~mcalabre. Red text indicates further development since the recent astro-ph preprint. As this paper presents a new projection, HPX (implemented in WCSLIB 4.0), for incorporation into the FITS WCS standard, it is presented here for comment by the FITS community. For those unfamiliar with the paper, the attached diagram based on Fig. 2 of Roukema & Lew (astro-ph:200409533), summarises it succinctly. (Please note that the ATNF web and ftp servers have downtime scheduled for 17:00 - 22:00 (+11:00) on 2005/02/11.) Mark Calabretta ATNF |
