Cylindrical map projection screwed up?
type: item
description: I've been doing some stuff using cylindrical map projections using set_map. So, darn it, I expect my lines of longitude to be vertical, and my lines of latitude to be horizontal in the image. But, when I set the LIMIT keyword to just look at a small portion of the globe, this is not the case. In fact, I only get a true cylidrical projection if the min and max latitude have the same magnitude, ie. -30 to 30 degrees. Is this a bug? or am I missing something obvious. I'm running IDL 5.1 on hp-ux 10.20 -Jonathan
