Hi Alex,
Well, the history here is a little odd: The residuals I have are only
for Fit 3 of the paper. This fit excludes reddened SNe, so it excludes
two Riess SNe (as well as two Hamuy SNe and one new HST SN). However,
in the stretch-luminosity plot I sent, most of the useful Riess SNe
were in fact included. It is just that several more of them could have
been included in the extinction-corrected stretch-luminosity plot if
I had those residuals.
Unfortunately, I don't have the residuals for Rob's
extinction-corrected fits. I just hacked something together using the
residuals without extinction correction along with the E(B-V)'s from
the paper. So for the extinction-correction case, what I showed was
somewhat incomplete. I would suggest waiting on the
extinction-corrected ideogram until we can get the residuals from Rob.
(Note that I have examined the ideogram without extinction correction.
I find that both high and low redshifts show a tail on the faint side
and a mode that is brighter than the mean. This is most likely a dust
signature.)
