[vsnet-chat 1957] Comparison sequence for SN 1997cy

[bas@lowell.Lowell.Edu (Brian Skiff)]

     In a paper available at the Los Alamos preprint server, and to be
published in the ApJ, Germany et al. provide a nice BVRI comparison sequence
for the southern supernova/GRB object SN 1997cy/GRB 970514.  There is a chart
but no positions for the stars.  Below is a list in the format of my large
photometric reference file.  The BVRI magnitudes of the source table have been
converted to V and B-V, V-R, and V-I colors.  The list is sorted in order of
decreasing brightness.
