The most important adverb is NMAPS=93.  In that case, with INVER=3 for 
example, all 93 facets will have to have a CC file version 3, or there 
will be problems.  It will switch to using images.  With INVER=0, a 
recent correction allows the highest CC version number to be used for 
each facet.  But that does not work for a specified INVERS.
