Reading Healpix and FITS files
Posted: October 10 2004
I'm unfamiliar with dealing with CMB maps.
I would like to be able to:
a) Take say one of the publicly available WMAP map files, and
extract the sky temperature as a function of pixel (and I'd really like
the pixel coordinates too..)
b) Take the FITS format output of say the Healpix routine anafast
and read the C_l's and alm's. I realize there are f90 routines
provided with Healpix which do this, but i'm using OS X and was
never able to get the relevant f90 routines to compile with all the
dependencies in the makefile.
What is the best way to go about doing this (short of being a FITS guru master)?
