By the way, i've never tested the script using lat/lon coordinates, but i suppose that you can get some of the parameters in a unit derived from degrees, which is not correct, so you need to use metric coordinates in order to get a suitable result. BTW, if you are willing to make a test on it and send (maybe privately) to me the results, I'll appreciate. Thus I'll update the documentation accordingly.
