What McIDAS command do you use to the the navigation as TEXT?  We have
not implemented the ADDE NAV stuff yet in Java.

i would like to be able to calculate several triangulations between 
satellite-sun-terrain (i.e. SZA, SAA, VZA, and VAA) for each swath/pixel to do 
atmospheric correction for CH 1-3. Now, i think i can organize some routines 
that can be implemented at client-side (read: java-jython-IDV). To start 
simple, can i access the orbital information or metadata (which may publish an 
average "viewing azimuth angle" for the whole swath) directly from the 
timeSequence in jython? Or do i need a TLE ADDE text server for that? Tom has 
an experimental ADDE server of NOAA data,

these zidv files are getting pretty big! ;-)
