      Derived maximum in some band is  (see above).

OBS:  ??? I got these from Peter Garnavich.

Date: 1997 () with 1997dec10 (344) for visible maximum gives:

I've put all the spectra I have on 97ef at my anonymous ftp site. You can get them by: ftp cfa0.harvard.edu username: anonymous password: your-email-address cd outgoing/peterg/sn97ef mget *.dat bye They are all ASCII two column spectra with the header at the top (which may or may not help). The spectra have been reduce in the usual way plus the spectra *** have been shifted to the rest frame *** and narrow emission lines removed. Let me know if you have any problems. Peter (Where I got all the 97ef spectra from. Note according to Iwamoto et al. (1999, astro-ph/9807060) the heliocentric velocity is 3400 km/s. This has been removed from the spectra according to Peter above.)
