The UVIOR bolometric luminosity of SN 1987A.

1) From Suntzeff et al. 1991, AJ, 102, 1118.

   Up to day 600 the error is about .03 dex (p. 1125)
   This about 7 %.
   But the relative error is only about .01 dex or 2.5 %.
   After day 600 somewhat worse.

2) From Bouchet et al. 1991, A&A, 245, 490.
   From Table 6.
   Supposedly the most accurate spectrophotometric data. 

Note these errors are exclusive of reddening and
distance errors.  The latter shouldn't affect
relative errror.
