My program already subtracts host galaxy, so Lifan's won't magically
turn this one into a Ia. It isn't true that there are no SN features -
look at my comparison plots. There are broad lines. I just wasn't
confident that any of the top three choices -- SN 1997dd (Ib/c),
SN 1991bg (Ia), or SN 1993W (II), are correct. None are a perfect
match, and when you get such variation in fits it isn't a good sign.
I can rule out 91bg by eye, because the broad Ti feature in the blue
is not present. I am pretty sure this is not a Ia. At any rate,
the host galaxy gives a redshift of z=0.242. So not only is this
a bad candidate from a type perspective, it is bad from a closeness
perspective, and, as you say, we may not be able to get enough
coverage.
