Chris,
I agree that we should take S01-035 out.
Also, I have refit S01-031 at z=0.777 allowing only E and S0 subtraction.
I think it is a probable Ia, if there is significant host contamination or
reddening (the original observation is very red -- my program has to
subtract a lot of host and deredden to make it fit a Ia). So Ia? -> Ia is
fine with me. A tar.gz file with postscript and text files of my
new fit are attached.
