We have developed a package of HEALPix based mathematical software, consisting of C, C++, Fortran90, IDL/GDL, Java and Python 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 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 facilities available and a large number of subroutines contained in the various libraries. It is available to the scientific community at http://healpix.sourceforge.net.
HEALPix was the format chosen by the WMAP collaboration for the production of sky maps (see http://map.gsfc.nasa.gov/news/index.html) from the mission data.
HEALPix software and format have been used by the HFI and LFI consortia of Planck collaboration for the simulation, analysis and data release of Planck data (see http://www.cosmos.esa.int/web/planck).
HEALPix software has been selected by the GAIA satellite mission currently surveying our Galaxy (see http://www.esa.int/Our_Activities/Space_Science/Gaia_overview)
