SPECTRUM LOG:

     JD times for the SN 1986g spectra of phillips1987 and cristiani1992.

     Bmax JD 2446561.5 +/- 0.5 (phillips1987) (1986may11.0) and cristiani1992 uses the same date.

     I believe all the spectra are observer frame.

     The cristiani1992 JDs may be rounded off to midnight UT unless they really were taking
     data near midnight UT which in Chile would be 8:00pm local time which
     near the winter solstice could be quite dark.
     The phillips1987g spectra were also taken in Chile and were mostly not far from
     UT midnight.
