Well, I guess wildly the literature you are unaware of 
holds better solutions, but that's an empty comment
as I don't know what it is. The idea that an age 
distribution is a bunch of little truncated 
Gaussians sitting next to each other on a line sounds
at best strange to me, but as I said I don't
understand what your problem is.
