Dear Diallists I've got two practical questions:
1. Let's say I have a photograph of a sundial. I do not know where it was originally located. Is there a way to discover the values of the declination and latitude it was designed for? There are clear hour and declination lines on the dial. 2. A friend of mine is helping a student in an attampt to reconstruct an old missing dial. They need a software which allows to make an animation of a shadow's path over the dial. Is there anything that would help them? I would be most grateful for any suggestions. -- Best regards Darek Oczki 52N 21E Warsaw, Poland GNOMONIKA.pl Sundials in Poland http://gnomonika.pl --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
