[vsnet-sequence 45] VRI sequences for active galaxies
Below are positions and VRI photometry for about stars in the fields of
twelve active galaxies measured by Bachev et al. The source paper incldues
finder charts but no positions for the stars; their table gives separate
V, R, and I magnitudes, which I show below as V, V-R, and V-I. Although the
quoted errors are a bit soft (~0.05), the colors appear quite consistent,
suggesting the results will be okay for rough zero-point adjustments. The
first line of each block is for the galaxy itself; the position sources
(column 's') are either the GSC-ACT (source G) or USNO-A2.0 (source A). I have
omitted stars in the field of Arakelian 120, which is better served by the
existing sequences by Hamuy & Maza, Henden, and others.
Most of these stars will be added to my large photometric reference file
