Ah, thanks for doing those numbers Greg. That makes sense, but I couldn't figure out how to get there. The blue does seem a tad long, but must be ok -> http://en.wikipedia.org/wiki/File:Li...e_spectrum.svg

Sorry, yeah I don't have a subscription to that either, but I found it on Google books via that citation -> http://books.google.com/books?id=Trc...page&q&f=false (type in page 339)

I actually haven't read it yet, so I'm not sure what the improvement is. Unfortunately, the google books scan has cut off the bottom of each page, so I don't know how coherent it's going to be.
