From his latet's plot, I agree that the R and I magnitudes could be
consistent.
However, it's still not clear to me that it's all based on the features.
It still just looks like he's chosen his continuum normalization
differently-- applying the function that pushes it a little up here, a
little down there, in comparison to what Serena did.
This is a case where one might do *better* to include higher-redshift
supernovae (i.e. up to 0.1), because you can break some of the
degeneracy that adding different broad wiggles into the spectrum. I'm
not sure if the way that Serena and I did this really takes care of
that. (I did it iteratively by fitting colors, making an uberspectrum,
using those for K-corrections, and repeating.)
