Sunny Day, When I first offered my web site on CD, I included a number of 3-dimensional virtual sundials, which are not available on the web site, as a bonus. I have now added a couple of additional items that some of you may find useful. As there are a large number of files, over 1150, which take up over 90 Mb of disk space, they are not available on my web site. The following summarizes what I am offering.
The CD now contains three sets of "Sun Charts". These charts indicate local apparent or solar time and the files are in pdf format. The first set of sun charts are generated in Cartesian co-ordinates and cover the range of latitudes from 90ºN to 90ºS in increments of 0.5º. As each sun chart covers a 6 month period of the year, two are required for each given latitude. A total of 722 Cartesian co-ordinate sun charts are provided for this range of latitudes. The second set of sun charts are generated in polar co-ordinates and cover the range of latitudes from 79.5ºN to 79.5ºS in increments of 0.5º. Polar sun charts above these latitudes are not provided as the plots are not very clear. Each sun chart covers an entire year. A total of 319 polar sun charts are provided for this range of latitudes. A third set of sun charts for particular locations including the North Pole, South Pole, Arctic Circle, Antarctic Circle, Tropic of Cancer, Tropic of Capricorn and the Equator are provided as a separate set. And that's not all! The CD also has a number of images of the "Dialling Buddy". There are 365 pdf files with images of the "Dialling Buddy" set at latitudes in the range from 90ºN to 90ºS in increments of 0.5º. There are a few special ones too. Having a real "Dialling Buddy" is a lot more fun but if you can't make one, for whatever reason, this is the next best thing. That's over 1400 "Sun Charts" and "Dialling Buddy" images available only on the CD. I would also like to remind you of the "Dialling Guides" available on my web site. There are a total of 81 templates that provide the layouts for 486 horizontal and vertical sundials. These can be obtained for free. It is very interesting comparing the "Sun Charts", "Dialling Buddy" and "Dialling Guides" for different latitudes. If you are new to dialling there is a lot you can learn. Happy Dialling!
