Wow. I've just pulled the mb and mv data from the Riess 1998 paper on
their high-z supernovae, and evaluated E(B-V) for the nine high-z
supernovae that they have dm15 lightcurve fits for. This is what I get
for their E(B-V) values:
SN E(B-V) dE(B-V)
-----------------------
1996E 0.120 0.226
1996H -0.208 0.085
1996I -0.174 0.113
1996J 0.213 0.071
1996K -0.055 0.095
1996U -0.164 0.121
1997ce -0.064 0.071
1997cj 0.039 0.071
1995K -0.116 0.106
It looks like those guys really were suffering from a mild "too blue
supernova" problem. Of course, when you prior it all away, you don't
have to talk about it....
(I evaulated these E(B-V) values by comparing their mb and mv values to
the values I get from my current favorite uberspectrum, and the
difference in the B template betwen day 0 and day 0.87 (the latter being
where my templates come to maximum in V).)
