The Hyperz package: overview
The public package contains the code to obtain photometric redshifts, called
hyperz and described in Section 3,
as well as a program called make_catalog, illustrated in Section
The second program is useful to build synthetic photometric catalogues
and to carry out tests on the attainable accuracy when recovering the redshift
given a filter set and a photometric accuracy (see Bolzonella et al. 2000).
There is no difference in the use of hyperz between observed and
simulated catalogues. Here we report the steps to retrieve and install
these programs and the ingredients used to build them. The source files
and the binary files containing template SEDs (see later) are available
on the web at the address http://webast.ast.obs-mip.fr/hyperz
and mirrored at the addresses http://www.ifctr.mi.cnr.it/~micol/hyperz
(but check the actual existence of these or new mirrors from the main page).
Take care to retrieve the files corresponding to the type of machine you
are using: for the source files you have to choose between the IBM version
and the default version, working on all other machines. Regarding the binary
files, the ``big endian'' standard works in general under Digital Unix
(with the compiler option -convert big_endian), SUN, HP, whereas
``little endian'' binary files have to be downloaded only under Linux system
or Digital Unix (without need of compiler options).
