Hi,

With 5529 computations go smooth and tracks are much better - see attached
HR diagram. Still, only type1 opacities are used here.

But then it is inconsistent. I mean we can use OP up to logT=8 and switch
to type2  for logT>8, but then, we have to use OPAL type2 tables, because,
as Aaron pointed, not only OP www goes only up to logT=8 (and does not
provide type2 tables), but OPCD software does the same.
