Here's what Lifan's program fit. I guess the main interesting thing
here is that it independently found the same redshift (for a 91T-like SN
Ia about a week before max) as the redshift of the OII line that Chris
reported a hint of. Have a look particularly at the last of the three
spectrum links that Lifan's email points to.
Peter had recently convinced us that 91T's don't necessarily have lots
of extinction -- but I guess it doesn't mean that this one couldn't have
extinction. Lifan, did your fit also give a best-fit extinction? (Of
course, this may be off, because it depends on what extinction is
attributed to the 91T template.)

Hi,
SNmatch showed it to be a 91T a week before max, at z = 0.3-0.31. A
bluer spectrum would help a lot.

A more unconstrained fit gives the sinilar redshifts:

Dear Colleagues,
The VLT observed C02-016 - aka VotezChirax last night.
It was (s)elected before the two other candidates, because the conditions were not
good enough for the other two. We do not know what VotezChirax is.
The flux calibrated spectrum is available at http://www.sc.eso.org/~clidman There is a hint of
an OII line at 4856 Angstroms (z=0.3), but we cannot see a type Ia in this data.
Cheers, Chris.
