   The problem considered is that of radiative heat transfer
   in a 1d plane-parallel slab in radiative equilibrium. The
   slab is of thickness L and the gray medium may absorb,
   emit and scatter radiation. At x=L the wall is a diffuse
   emitter and reflecter kept at a fixed temperature. At the x=0
   the net radiative heat flux Qrad is specified at the wall.
