The absorption of photons is distributed as a density over space in some way (along a path, exponentially decaying with distance if the absorption cross section density is constant over distance; if their is (partial reflection), it may be along a bent or branching path; if there is scattering, the distribution may fill a volume.

EWF is a density over distance along a line (in the absence of scattering, etc.) or lines (when partial specular reflection occurs), or a density over volume (when scattering contributes to the CSD), where the sum over all space = 1; it matches the distribution over space of the absorption of a unit amount of radiation incident at L from the opposite direction.

It is hypothetically possible to have populations of different temperatures within the same volume; as long as each seperate population is at LTE within itself, the radiative physics as described above can apply in a modified way — for example, the density distribution of an EWF would have to be distributed over space and over the different populations within that space.)
