We have developed a package of HEALPix based mathematical software, consisting of Fortran90 and IDL source codes as well as documentation and examples. Successful installation produces a set of facilities using standardised FITS I/O interfaces (http://heasarc.gsfc.nasa.gov/docs/software/fitsio) as well as two Fortran90 libraries which users can link to their own applications. Among the tasks performed by the components of the HEALPix package are the following:
The package includes documents which describe the installation process, the Fortran 90 facilities, the IDL facilities and a large number of subroutines contained in the library. It is available to the scientific community at http://healpix.sourceforge.net.
HEALPix is the format chosen by the WMAP collaboration to be used for the production of sky maps (see http://map.gsfc.nasa.gov/news/index.html) from the mission data.
HEALPix software and format are used by the HFI and LFI consortia of Planck collaboration for the simulation, analysis and data release of Planck data (see http://www.sciops.esa.int/index.php?project=planck).
It is also being used to analyse the data provided by the balloon CMB missions Boomerang (see http://cmb.PHYS.cwru.edu/boomerang/ or http://oberon.roma1.infn.it/boomerang/) and Archeops ( http://archeops01.free.fr/main_archeops/index_english.html).
