       SUSPECT Index:  SN 1996X Ia.
       There are 16 SN 1996X spectra:  the two 1996apr17 spectra seem to be exactly the same, 
       and thus not 17, but 16 spectra.  
       These are probably all observer frame since the telluric line seems to
       be in the observer frame and salvo2001 plotted observer frame.

       wang1997 Spectropolarimetry and
       a high S/N spectrum for 1996apr14.3 UT.
       This spectrum may be slightly better than the salvo2001 spectrum because of its high S/N
       obtained when doing spectropolarimetry.

CORRECTIONS:  Heliocentric velocity 2033 +/- 22 km/s (2007jul11) from 
              NGC 5061 (Leda).
              See also NED
              where the heliocentric velocity is 2065 +/- 46 km/s.
              I'll trust Leda just for consistency.
