The latest version of the HEALPix package (3.10) offers the following new features: Bug corrections and Improvements in Version 3.1 General N/A C * experimental GNU autotools support (undocumented); the standard configuration script remains available C++ * Spherical Harmonics Transform library libpsht replaced by libsharp (Reinecke & Seljebotn, 2013). Note that some gcc versions (4.4.1 to 4.4.6) crash with an internal compiler error during compilation of libsharp. The problem has been fixed in gcc 4.4.7, 4.5.*, 4.6.*, 4.7.* and newer versions and was not present in versions 4.2.* and 4.3.*. * added boundaries() method to T_Healpix_Base * experimental GNU autotools support (undocumented); the standard configuration script remains available Fortran 90 facilities and subroutines * all Fortran facilities now support most of cfitsio's ``Extended File Name Syntax'' features, allowing the reading and processing of an arbitrary HDU and table column out of remote, compressed FITS files. For example, setting infile = ftp://url/file.fits.gz[extn][col colname] in anafast will download the FITS file file.fits.gz from url, uncompress it, open the HDU (extension) featuring keyword EXTNAME=extn, or the one with 1-based rank number extn, read the table column with TTYPE*=colname out of it and will analyze it. It is also possible to perform a remote anafast analysis of a Planck Legacy Archive (PLA) sky map named map.fits via the PLA AIO Subsystem by simply setting infile=http://pla.esac.esa.int/pla/aio/product-action?MAP.MAP_ID=map. fits as input map file. * yet faster synfast, anafast, smoothing thanks to libsharp routines (see warning on gcc releases above). IDL * bug corrections: query_disc: correct handling of empty disc; bin_llcl: correct handling of optional argument. * double precision of input now preserved in gaussbeam and euler_matrix_new. * fits2cl: addition of /PLANCK1 keyword to read best fit C(l) model to Planck 2013 + external data. * it is now possible to read a specific FITS file extension identified by its (0-based) number or its case-insensitive EXTNAME value with the Extension keyword added to fits2cl, getsize_fits, read_fits_map, read_fits_s and read_tqu. * update of the required IDL-astron library routines, and their supporting Coyote routines (2013-02-08). Java N/A Python switch to healpy 1.5.0: addition of gauss_beam to generate Gaussian beam window function.
