Reynald,
C02-000 Assurancetourix looks great from a spectroscopy standpoint -- it
is an obvious Ia. I do not think we need to revisit it, since there are
other SNe that should take priority from a scienntific point of view.
It looks like it was caught after max, judging from the light curve.
C02-008 looks like a good Ia as well, and I don't think it needs another
spectrum. Note that you (and SN Trak) call it Abraracourcix, but I have
listed as descenteaHaurix2, whatever that means.
I think there are other CFHT SNe that may be in need of better
spectroscopy though.
Below I list all of the CFHT SNe with light curves and what I think of
their spectra:
SNe with no spectra:
C02-001 Bichomabix: No spectrum. Too faint now?
C02-013 Isntix: No spectrum. This was on the list for quite a while --
have we given up on it?
C02-029 Comix: No spectrum. If you throw out the first point the LC is ok.
C02-032 ItneedAfix: No spectrum. Not a good light curve. Not worth
the time.
PastMax5: Past max. No spectrum, but not worth the time. LC is past max.
C02-033 Philanthropix. No spectrum
SNe for which another spectrum would be useful:
C02-028 Prolix: The spectrum is certainly not conclusive as a Ia. It
may be dominated by galaxy light. It is possible that a second spectrum
could help. z=0.448
C02-016 VotezChirax: Its heritage is disputed. If we are going to use
this, we need another spectrum. May be SN 1991T-like, which would also
make it interesting. Then again, it may also be reddened, which would
mean it is not worth trying. Peter recommended not spending any more
time on this. I would agree with throwing it out, but again, if you are
going to try to use it, then another spectrum is necessary.
SNe that have spectra, but don't look like Ia's:
C02-030 Troudux: Not a Ia? Chris says no obvious features in the
spectrum, which is blue. I agree with Chris. No point in getting
another spectrum of this one.
C02-034 InTheMix: Probably not a Ia. No light curve? Not worth
spending time on.
C02-027 Found in cross-telescope subtraction. No clear SN features.
Not worth spending time on.
Forgotten SNe:
C02-026 cand0015 Found in cross-telescope subtraction. No spectra.
What does the light curve look like? Did the French find it?
Whatever happened to C02-014 Falbala, and C02-015 Alambix?
So are you not planning on doing anything with the ones without spectra?
What about C02-016 or C02-028?
