c class function 
c ========================================
c 

This model has a very high iron abundance, 100x H, and most Fe is
in the form of Fe+. it has intermediate density and should produce
and FeII spectrum something like an AGN.
 
The set line precision 6 increases the number of significant figures
in the wavelengths for each line.  This is needed to get the right
FeII inward band.
