Eric - we did MNJ, got new FLATN, nice new adverbs, etc.   Attached are 
my inputs.  The output map from this is, as expected, a 200x200 image
with 240" pixels, and the data properly interpolated onto the map down 
to a declination of just below 26degrees, which is the lowest 
declination in the  first input map.  Same problem as previously.  
Advice welcome!  Thanks.
