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.

The idea behind the matching of lists is to form a set of triangles

from the points in each list, and look for similar triangles.

The algorithm used in version 0.15 and 0.16 is based upon the article

"Fast Algorithms for Matching CCD Images to a Stellar Catalogue"

by Vello Tabur, Publications of the Astronomical Society of Australia,

vol 24, page 189 (2007).  See the following URL (which should

all be entered on one line)

INSTALLATION

Follow the standard installation procedure:

  - uncompress the gzip'ed tar archive

  - cd match-0.16

  - ./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 "match.html" for a description of the 

programs, the input and output formats, etc.

REQUIREMENTS

The software is written in ANSI C, and requires nothing beyond the 

standard math library.  The selftest script is written in Perl;

it works with Perl 5, but fails with Perl 4.

NOTES

The pre- and post-processing steps assume that celestial coordinates

are expressed in decimal degrees, not sexigesimal notation.

That is,

        this:   233.0082           not this:  15:32:01.9

Incorporating support for sexigesimal notation is probably a Good

Idea for some future release.
