My comments on the WIYN SNe are below. I think T02-029 is at too low a
redshift to be useful. I am sure it is at z=0.21. This is the one that
Chris had labeled "Odd!" Chris, can you clarify what you meant by that?
Am I missing something?
Also, I am not as sure as Chris that T02-028 is a Ia, nor am I convinced
that S02-064 is
a Ia, but that is an old argument.
Bottom line: 2 rock solid Ia's, 2 things that probably are Ia's, but
might not be,
3 without spectra, and 1 Ia that should be replaced because z is too low.
S02-064 Still a toss-up whether this is a Ia or a Ic
S02-058 No spectrum
T02-030 Great Ia near max, z=0.511
T02-028 Fits Ia and Ib/c almost equally well. I think I might be able
to convince myself
that there is a dip at 4000A Si, indicating a Ia, but it
is not obvious. Either is was
10 days or so after max (SN rest frame) on May 18.
T02-037 Ia at z=0.49
C02-029 No spectrum.
T02-047 No spectrum.
T02-029 Ia at z=0.21
