Well, hard to say without more investigation. I'm never particularly
optimistic when it comes to IDL map projections, though. They always
seem to be doing something different from what I *think* they should be
doing. :-)

More or less, yes, but I'm still not absolutely convinced the problem is
in the map projection part of the code. In any case, have to run. One of
the kids has strep and has no "soft" food in the house. Running to the
rescue now. :-)
Cheers,
David
