The adverb NCOMP is only 50 in size.  We had assumed that one would not 
want to specify a specific number of components for so many fields - 
there could be 4096 of them.  I suggest that you use the FLUX adverb or 
set NCOMP large.  I do not recommend cutting off at the first negative 
unless these CC files have been compressed (which IMAGR does for OVERLAP 
1 and 2).  Even then it is debatable whether you should do this.
