Hello Helmut, I hope you don't mind me sharing this note with the mailing list.
I am helping my grandson with a science fair project and he is interested in making a cylindrical sundial. Really, it was his suggestion. I know the theory for altitude dials but needed to provide a specific design for his location. I was pleased to find that your program "Sonne" includes cylindrical or Shepherd dials as one of the options available. Excellent! After checking the version distributed with the NASS Compendium, I downloaded the latest version from your website. http://web.utanet.at/sondereh/sun.htm I am very pleased with the performance of the program. It allows me to specify the location and size to get a specific design. It allows for local or time zone time. This is great. My design problem is now almost completed. Thanks for making the program available. I have not spent much time learning all the options but I did find the English/German option. This is a great help for people like me with limited language skills. My only problem so far is the equation of time correction. I could not find this option for this type of sundial. Has it been included? Did I miss it? Has any one else included this option in a similar program to give "standard time" on a cylinder dial?
