An interesting article: Nic Suntzeff said that one of their ESSENCE
students tried coding this algorithm up, and got *much* better signal to
noise for some sample high-redshift SN spectra. (Apparently on SN went
from being a confusing thing that looked like it was at redshift z ~ 0.8
to being a very clear SN Ia at z = 0.43!)
