photom v0.7 - by Michael W. Richmond (C)opyright 2001-2003, Michael W. Richmond, all rights reserved This package contains software to match one list of objects against another list, allowing for arbitrary translation, rotation, scaling, and some distortion. The code is designed specifically for astronomical data: list of stars or galaxies. There is a small "pre-processor" to put astronomical data into the proper format for matching, and a "post-processor" to apply a transformation to the astronomical coordinates in a list. Most of the real work is done by the "match" program itself. INSTALLATION Follow the standard installation procedure: - uncompress the gzip'ed tar archive - cd photom-0.6 - ./configure - make If your system has Perl installed, you can run a quick self-test: - make check The test assumes that Perl is located in /usr/bin/perl. If it's somewhere else, simply type - perl selftest.pl See the documentation in "collate.html" and "photom.html" for a description of the programs, the input and output formats, etc. REQUIREMENTS The software is written in ANSI C. It requires several routines from the GNU Scientific Library (GSL) of mathematical routines: see http://www.gnu.org/software/gsl/gsl.html. The selftest script is written in Perl.
