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 4. 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.mi.iasf.cnr.it/~micol/hyperz and http://andorra.astr.tohoku.ac.jp/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).
