I have just posted HydroLight Technical Note #6 (file
HTN6_infdeep_sources.pdf). This note discusses the sometimes puzzling
behavior of the light field near the lower boundary of the water
column in runs that use an infinitely deep water column and also
include inelastic effects (fluorescence or Raman scatter) or
bioluminescence. A work-around for H version 4 is given. This
work-around will be automated in version 5.
