VRI comparison stars for selected active galaxies.

BACHEV R., STRIGACHEV A. and DIMITROV V.

Abstract (from CDS):

We present V (Johnson) and RI (Cousins) magnitudes of field comparison stars for 12 bright Seyfert galaxies. These stars are closer than 6' (typically 3'-4') to the galaxy and have V magnitudes between 10mag and 6mag. The sequences could be used for CCD monitoring and differential photometry of these active galaxies, aimed to better understanding the physics of their variability. Photometric errors of measured stars are in the range 0.03mag-0.06mag . Finding charts (15'x15') are also included.
