Dear Jonathan I'm not familiar with the Lambertian equivalent albedo. Probably this was explained when we discussed it before and I have forgotten! However what you write makes sense to me and the names look OK, apart from a minor point that I think cosine_of would be better, like square_of, derivative_of and other phrases naming functions.
I expect the previous discussion got overlooked accidentally. Sorry about that. If no-one has any concerns now, Alison will consider the names for inclusion in the next release of the table, in due course - she does this quite frequently.
