David,
I don't think you're off the hook yet, I've looked at this issue and do
see this problem in all recent versions of GAIA that I have, i.e. I read
acfits.sdf into GAIA and it fails badly during an astRead, badly enough
that I cannot tell anything about what's going wrong (there are also some
indications that this is bad enough to effect the working of the debugger,
so I'm worried there's a buffer overrun somewhere). I'll persist looking
at this until I can point you at something more definite.
BTW, an observation. When reading in this WCS NDF creates a very long
LutMap to describe the axis values (8192 elements) which I pass into and
then back out of various channels, this takes a significant amount of time
(even on my Athlon 2800+), when in actual fact the LutMap can be simplied
to a WinMap. Any chance of NDF GTWCS performing this simplication before
the WCS gets out of NDF?
Peter.
