In this document the installation procedure for the HEALPix distribution is outlined. HEALPix comprises a suite of Fortran 90, C++ and IDL routines (together with one C-library which is also provided) providing both stand-alone facilities and callable subroutines as an alternative for those users who wish to build their own tools. A set of C and Java subroutines and functions is also provided.
The distribution can be downloaded as a gzipped and tarred file,
which can be unpacked by executing the commands
% gunzip Healpix_2.00.tar.gz % tar -xpf Healpix_2.00.tar
The unpacked distribution has a directory structure as shown in Figure 1.
As with most freely available software, the distribution
comes with caveats, the major one being that although we have attempted
to automate the installation as much as possible, not all eventualities
can ever be foreseen. We have tested the installation on the following
platforms:
AIX, IRIX, IRIX64, Linux, SunOS, ALPHA and Darwin
There may be problems in the facility build due to the local system configuration which is beyond our control.
