I'm not sure, but I do remember a recent thread on sources of high-grade
gratings on this very list as a matter of fact! I think one of the folks
from our California Contingent was able to provide some info? Anybody?
By the way, Edward, do you analyze and publish your own meteor spectra
somewhere? Or is there a group within RASC or IMO studying compositions?
Clear spectral lines!
