Hello, i'm an astrophysics student, and i need to create a CMB map using Planck data. I have to use Healpix on IDL. I'm new in IDL, but i'm learning the basics, and i haven't particular problems. My problem is with Healpix: i can't understand what is the right procedure of installation (on Windows 7). I followed the guide but i can't complete it, because is mainly focused on Linux systems. I don't know what to do after installing cgwin and all the requested packages. The guide is here: http://healpix.jpl.nasa.gov/html/install.htm#SECTION00071000000000000000 Is there someone who has already installed it on Windows? Thanks for your attention.
