Sorry. Yesterday was a very busy day at work. I have never worked
with .arf files before. I ordered some panchromatic imagery from a
company called Sensiac. The data was all sent in movie files in
this .arf file format using a program called ImageJ made from NIH---
it's a free viewer comparable to IDL and ENVI apparently. Anyway, I'm
used to not having problems bringing in files into ENVI. Now I have to
do it via IDL and I'm not sure how to do it. Funny how you'd think
attending the IDL courses I'd know how to bring in a simple file into
ENVI after converting it in IDL, but they never taught that crap. I
guess they figure teaching things like addition and subtraction of
variables like 2+2 is more valuable than bringing in data.
