It is not that I have not read your web page. In fact, I looked it very
carefully but still have doubts.
In addition, I have also read Isobel and Chris's original notes:
>Chris: 98109 was very faint. It was not clear what type this SN was.
>Isobel : Looks like a Ia at z=0.5. If the line is OII then z=0.497
>Chris again(Jul 01) I've had a look at the 2-d and 1-d spectra and it
>is ulikely that the feature we see is OII. It is probably a reisdual
>from the bright OI sky line at 5577 Angstroms.
It does not seem conclusive to me that the redshift is determined by these
notes.
There are a lot of good reasons to doubt the identification of a Ia based
on spectrum with a S/N ratio of around 1.5. However, I would still agree
that this is likely a Ia, especially if the host contribution is very small.
Cheers,
Lifan
