   The problem is as for case 201; but now allowance is made for
   absorption and emission by the medium between the two plates.
   The gap between the plates is WG (default = 1.0), and the
   absorption/emission coefficient of the medium is EMISS.

   The exact solution for the heat flux is:
         QRAD = (EH - EC)/(0.75*ROSS*WGAP + 1/EMISH + 1/EMISC - 1)
   where EH and EC are the black-body emissive powers of the hot and
         cold surfaces, i.e. temperature**4 * Stefan-Boltzman
         constant;
         ROSS=(EMISS+SCATT) is the Rosseland coefficient.
         The ROSS*WG product gives optical thickness of the gas slab
