version 0.3 12/13/2004 Major improvement: replaced Numerical Recipes routines in "solvematrix.c" with equivalent SVD routines from the GNU Scientific Library (which is now required to be on your system) Also fixed very minor bugs in the selftest.pl script. version 0.2 11/21/2004 Minor improvements: can now handle more stars (10000) and images (3000) matrix is now built more efficiently, without including stars and images which are not part of the solution solvepht's "min=" and "max=" options now work properly version 0.1 11/08/2004 Initial release of the package. Includes the two main programs "multipht" and "solvepht", plus a test Perl script "selftest.pl". The current code uses a somewhat fragile set of routines to handle the matrix algebra in "solvematrix.c". It will fail on some -- but not all -- machines if compiled with option "-O2", which is the default in many cases. I have arranged the distribution so that the compiler flags are forced to be "-g -Wall" to prevent this from happening. The long-term solution is to replace these routines with more robust code, perhaps from the GNU Scientific Library.
