Software for pixelization, hierarchical indexation, synthesis, analysis, and visualization of data on the sphere

HEALPix (Hierarchical Equal Area isoLatitude Pixelization) is a software for pixelization, hierarchical indexation, synthesis, analysis, and visualization of data on the sphere of a sphere. As suggested in the name, this pixelization produces a subdivision of a spherical surface in which each pixel covers the same surface area as every other pixel.

Another property of the HEALPix grid is that the pixel centers, represented by the black dots, occur on a discrete number of rings of constant latitude, the number of constant-latitude rings is dependent on the resolution of the HEALPix grid.

What's New in This Release:

general:
· installation...
· Fixed IDL installation problem under (ba)sh
· Check consistency of cfitsio library with F90 routines
· introduced command line options for ./configure
· fixed infinite loop in main Makefile\'s tidy and distclean options
documentation:
· ``IDL routines\'\': rightfully says that IDL6.0 or more recent is required

C:
· Makefile no longer assumes that current directory (\'.\') is in PATH

C++:
· fixed error affecting equatorial pixels in maps generated by alm2map* Fortran90
· fixed problem with TTYPE* when writing FITS header (was also affecting IDL\'s isynfast)
· fixed crash causing bug in map2alm_iterative subroutine (was affecting anafast, sky_ng_sims and smoothing facilities)
· fixed un-initialized variables in compute_statistics subroutine
· fixed parameters parsing problem in interactive mode of synfast, anafast, ...

IDL:
· issues warning when non-integer pixel indexes are fed to nest2ring, ring2nest, pix2ang_*, pix2vec_*, ...
· more stable and elegant behaviour of isynfast and ianafast
cartview, gnomview, mollview, orthview:
· deal properly with MIN and MAX in ASINH mode
· polarization norm map can be offset ( POLARIZATION=1 mode)
· original color table and plot settings are restored when leaving these routines
ximview:
· fixed problem with cut-sky FITS files
· color scale bar added to PNG output
· cosmetic editions to remove_dipole

System Requirements:

No special requirements.
