An extensive HTML documentation is included in the package (in [HEALPix]/doc/html/main.htm). It is also available at the web page
http://healpix.jpl.nasa.gov,
as well as the PostScript documention.
The convention used for the normalisation of the polarization power
spectra has been changed to match that of CMBFAST. This subject and its
implications are described in details in the HEALPix
Primer
The pixel window functions are now provided for both temperature and
polarization. Recalculation of the temperature window for
Nside > 128
induce a slight change of these functions (see the ``HEALPix
Primer''
for details).
Because of its obsolete F66 features that limited its portability with
current f90/f95 compilers, the FFTPACK module used in
version 1.10 is no longer in use. HEALPix 1.2 can either use a different
self contained FFT module shipped with the package, or
use the freely available FFTW library (see section 2). The script file asks which FFT the user wants
to use. If selected, FFTW must be correctly installed (in double
precision) before installing Healpix.
It is now possible to use an OpenMP parallelisation of the Spherical
Harmonics Transforms (see § 2).
The compilers now supported under Linux systems are
Intel Fortran Compiler, available for free
http://www.intel.com/software/products/compilers/downloads/forlin.htm
(tested for version 5.01, 6.01 and 7.0)
Lahey/Fujitsu Compiler, both free trial and
commercial versions
http://www.lahey.com/linux.htm
NAGWare f95, commercial http://www.nag.co.uk/nagware/NP.asp
Portland Group Compiler, commercial http://www.pgroup.com/
Fujitsu Compiler, commercial
The Mac Operating System Darwin is now supported. To
this date (Jan 2003) it has only been tested with NAGWare f95 http://www.nag.co.uk/nagware/NP.asp.
A small subset of routines for the pixel to sky coordinate conversion
is now available in C (see the documentation ''C Subroutines Overview'').
New Fortran subroutines have been added or upgraded (see the documentation
''Fortran90 Subroutines Overview'') and
most of the Fortran facilities have been upgraded (see the documentation
''Fortran90 Facilities User Guidelines'')
several Fortran routines have been renamed and merged.
The module wrap_fits has been renamed head_fits to reflect its
extended capabilities,
some routines no longer in use have been moved to obsolete module
New IDL routines have been added, and several routines have been renamed
or merged. See the documentation ''IDL Facilities
Overview''
The configure script automatically creates a (system specific)
profile defining useful environment variables and aliases. In
particular, the system variable HEALPIX must be correctly
defined (as the full path to the HEALPix directory) prior to running the pipeline.
All legacy f77 or f66 codes have been removed or replaced in
order to improve the portability
The script file has been improved to, among other things, get rid of problems
appearing under SunOS
