I'll take a look. I just posted above yours with a more insightful set of 
data than the first three pointer. Yes, some way of bisecting, or chopping 
is the trick here. One is just trying to fill in all the gaps with 
interpolation and produce 360 points to feed to the telescope software. It's 
sort of like giving someone, and forgetting interpolation here, the sequence 
20, 30, blank, 60, 70, 80 and asking for the two missing tens between 30 and 
60. 40 and 50, of course.

The fellow above wrote an interpolate function that will probably fit the bill.
