Evil Dr., just curious... What are you trying to do with the data? Habital locations?
Didn't notice this earlier...
A planet someone was building on one of the worldbuilding boards I frequent (which is where most of the weird questions I ask here originate from) got me wondering about this - he had a bunch of low-tech people living at the poles of a rather inhospitable desert world whose temperatures were rather high. It had a 14 degree tilt though, and I was curious as to how long the day/night would be there and whether in practise it would actually be that much more habitable at those latitudes because of that. I suspect it wouldn't be...
