Software and Products for Analysis of Planck dataHere are a set of software tools and data sets that will facilitate use of the Planck Data Release 1 products. These tools address work with the all-sky HEALPix-formatted maps and with the source catalogs. All-sky map functions include generation of local tangent plane projection for ingest into tools such as ds9, general aperture photometry directly on the all-sky maps, and convolution of user HEALPix maps with the Planck effective beams. Source spectral energy distribution dependent color-correction calculations and map unit conversions are provided to supplement the analysis of the source catalogs and photometry.
More information and software tools for analysis and display of HEALPix maps can be found at http://healpix.sourceforge.net/.
The likelihood code [see under Other Tools] is a C library containing codes to compute different approximations to the Planck likelihood, which the user can use to test a cosmological model of their choice. Wrappers are provided so that the functions can also be called from Python and F90.
