[fitsbits] HPX projection
Greetings, This is a reminder that "Mapping on the HEALPix grid" by Calabretta & Roukema, is available from http://www.atnf.csiro.au/~mcalabre. This paper describes the HEALPix (HPX) projection for addition to those of WCS Paper II. Some changes have been made to the draft announced here on 2005/02/11 (indicated in red in the current draft dated 2005/06/15), principally in disclosing the relationship of HPX to the Collignon projection. If you have any comments on the proposal to incorporate HPX into the FITS standard then now would be a good time to make them. Mark Calabretta ATNF |
