Sundials

This program allows to build a sundial; it gives all necessary data to draw hour lines, solstices lines, equinoxes line and analemna line.
The user have to insert the following basilar information:
latitude of the place where will be fixed the sundial: values from -90° up to +90°;
zenithal distance of the stylus (this is perpendicular to plane of the sundial but the program gives information if you want to use a polar stylus): values from 0° (horizontal sundial) up to 90° (vertical sundial);
gnomonic declination: values from 0° up to 360°;
length of the stylus: values from 1 cm up to 1000 cm (10 meters - the top of the stylus could be an hole in the ceiling of the church!);
width and height of the sundial: values from 10 cm up to 10000 cm (100 meters); the points that fall out of these limits will not be computed;
hour line for analemna: integer values from 6 up to 18.
The program uses the registration based on HotSyncName.
Note: NOT YET for Palm OS 5.0
