The error is found In Section 5.2 (Physics Processes) subsection Optical Photon Processes in the third paragraph of the subsubsection "The UNIFIED model". It can be found on page 255 of the PDF version and is also in the same location onthe web version. Details: In the discussion of the UNIFIED opticalsurface model, optical surface parameters REFLECTIVITY and TRANSMISSION are used in several places. However, the name of the second parameter should not be TRANSMISSION, but rather TRANSMITTANCE.
Alex/Koichi, please assign this to me.
Thanks, John, for reporting this. It is now fixed (but changes won't be visible until new documentation is released in December).
