SPECTRUM LOG:

     JD times for the SN 2002cx spectra of li2003 
     Bmax from li2003 where the JD Bmax is JD 2452415.2 +/- 1.0 (p. 457)
     which is 2002may20.70 UT.

     Unfortunately, li2003 only provides whole number dates, and so
     some of the JDs' below are just placeholders until the real ones are
     available.

     The first 4 spectra have JD from the FITS headers of the 
     cfa supernova archive spectra.

     The next 5 were taken at the Keck telescopes in Hawaii which is 10 hours = .4 days
     behind UT.  Thus, .4 UT is midnight in Hawaii.  Thus, the others were .4 +/- .3 UT.
     That's the best estimate I can make right now.

     As  far as I can tell all the cfa supernova archive spectra
     are in the observer frame.

     The spectra from David Branch's directory /home/branch/synow/sn2002cx
     seem to be all in the rest frame.
