Mr. Ossipoff:

It sounds like this list does not welcome general map projection 
chatter. The ICA Commission list is out of service because of problems 
with our hosting organization. You are welcome to subscribe when it is 
back in service.

What made the determination of Aitoff's scale variation difficult for 
me was the fact that I was trying to make it easy, by the sort of 
informal approach that I'm used to with simper projections. Apparently 
with Aitoff there's no substitute for actually writing X and Y as 
functions of lat and lon, and then differentiating X and Y with 
respect to lat and lon.
