Subject: SN1993J photometry
I have tried to compile presently avaialble photometry of SN1993J
in addition to those sent from B. H. Granslo (Norway).
For photoelectric photometry with mentioned comparisons, I have tried
to reduce them using suggested photometric standards rather than GSC
magnitudes. Such data are denoted as "corrected mag".
Visual observations from Japan have also been reduced using V sequences
in "Supernova Search Chart" (designated as SEQ="TB").
The compilation is only very preliminary and may contain errors.
Consult the original data sources for quantitative analysis.
Observations marked with * are privately communicated. Please omit IAUC 5742
