Computation of lighting-relevant values

Some programmes useful for lighting evaluation purposes

will eventually be placed in this directory. At present, there are just

An example of its output is mach.png, a map for the January 2005 comet Machholz, made by the map.php by writing
 @mach.cnf np o wpmach.eps d5.1.2005 t20 ut0
on the command line and checking the box ``override'' (in fact, I've deleted most of the deep-sky objects from mach.eps and remade the png and pdf files). The times are UTC (comet positions as passing near Pleiades, each ``European'' evening).

(February and March comet positions produced similarly with a command line
 @mach.cnf np o wpmap.eps ra15 de80 d8.2.2005 t20 ut0 $s2 $n30 m800
and less editing are the files mach2.*, e.g. mach2.png.)
