摘要
We present a list of photometric VRI comparison sequences in the fields of 16 blazars. For six of these objects, comparison stars were calibrated for the first time during the present work. For most of the other 10 blazars, we improved the old sequences by either calibrating stars in the R and I bands or adding new comparison stars. Finding charts for 15 of these sequences are also reported.
