Okay.  For IMGLIST, it's just a matter of printing out
the comment cards.  What I really need is this as "numeric"
information.  Right now, we get some of this by parsing
the comment cards and getting numeric values for center
lat/lon and calibration units.  How standard is the
format of the information for the Level III imagery so
it could be parsed if need be?

One confusing thing is that AUX=YES does not get you the
AUX block.  Does it get the comment cards also, or is
that automatic with any ADDE request?

Okay.

That'd work for me.

Thanks.  I've come across some other things, so I'll
come talk to you about them.
