The linear combination WMAP map is here: http://lambda.gsfc.nasa.gov/data/map/ilc/ http://lambda.gsfc.nasa.gov/data/map/ilc/map_ilc_yr1_v1.fits I can email anyone packages for reading this in - the "healpix" software is non-free software - i haven't put my version online since it's "non-free" in the Debian sense, though i would be happy for help to make it "free" (GPL compatible etc) if someone had the time... (or if i have 2-3 days free) For now, it's probably not a priority. boud
