From pence@tetra.gsfc.nasa.gov Fri Oct 20 10:51:10 1995 Path: solitaire.cv.nrao.edu!mail-to-news-gateway From: William Pence Newsgroups: sci.astro.fits Subject: WCS keywords for alternate image representations Date: 20 Oct 1995 10:04:51 -0400 Organization: National Radio Astronomy Observatory Lines: 19 Sender: daemon@solitaire.cv.nrao.edu Message-ID: <199510201403.KAA13748@tetra.gsfc.nasa.gov> This is to announce that a revised version of the paper that describes a WCS keyword convention for images that are stored in FITS tables is now available at ftp site legacy.gsfc.nasa.gov in the files /software/fitsio/wcs_keywords.tex and /software/fitsio/wcs_keywords.ps This short document is intended to be a companion to the main WCS proposal by Eric Greisen and Mark Calabretta, and describes the analogous set of WCS keywords for images stored either as a 2-D vector element in a binary table, or as a list of pixel coordinates in a table (similar to the IRAF QPOE format). This convention has been used for some time now within the high energy astrophysics community, so we hope that this proposal can be reviewed and acted on more or less in parallel with the Greisen and Calabretta paper. -Bill Pence HEASARC/GSFC
