Abstract
We present a list of photometric VRI comparison sequences in the field s of 16 blazars. For six of these objects, comparison stars were calib rated for the first time during the present work. For most of the othe r 10 blazars, we improved the old sequences by either calibrating star s in the R and I bands or adding new comparison stars. Finding charts for 15 of these sequences are also reported.
