CORRECTIONS: Heliocentric velocity 3899 +/- 3 km/s (2007jul02) from
UGC 272 (Leda).
Asiago gives 3878 km/s.
Galactic foreground reddening E(B-V)=0.10/4=0.025 reddening from
UGC 272 (Leda).
This is derived from
Schlegel et al. (1998)
OBSERVATIONS: From
1) SUSPECT has 0 spectra.
2) Eddie Baron has 1 spectrum from 2005nov05 from phillips2007.
3) David Branch has probably all the spectra of phillips2007 (/home/branch/synow/05hkphillips).
4) David Branch has probably all the spectra of stanishev2007b (/home/branch/synow/05hk),
but these are still not for publication.
SPECTRUM LOG:
JD times for the SN 2005hk spectra of phillips2007 and eventually stanishev2007c.
Bmax from phillips2007 is JD 2453685.1 +/- 0.5
Bmax from stanishev2007b is JD 2453i684.5 +/- 0.5.
Both groups are experts and so for the time being I adopt phillips2007.
The phillips2007 spectra are not deredshifted relying on the Ca II triplet minimum in
the last spectrum.
And also on the day -3.4 Si II line absorption which in the phillips2007 Figure 2
seems to minimize at 6200 A which agrees with my plot when I redshift it appropriately.
Note the dates and wavelengths below rely on phillips2007 directly.
