FOund this thread on PL on the subject. It doesn't have the data in it, but it does say who to ask about it.
I also notice that that calculator doesn't agree with chroma on equivalent brightnesses. RHD's calculator says 1W of 532nm is equal to just under 30W of 445, where as chroma shows it as 20W of 445 as having the equivalent brightness.
So I think there is some math missing somewhere.
