The directions in H are defined by the partitioning of all directions
into "quads", as shown in Fig 2 of the Users Guide, and as described in
section 2.4 of the Users Guide. These directions/quads are the same
above and below the sea surface. Thus, for example, if the sun is in a
particular quad above the surface, its refracted beam will be in a
different quad below the surface (for a level surface). Let me know if
this doesn't answer your question.
