Simultaneous UBVRI photopolarimetry of three blazars: 3C 66A, S5 0716+714 and OJ 287.

Abstract (from CDS):

We present new photopolarimetric observations of three well known blazars, 3C 66A, S5 0716+0714 and OJ 287. All these objects show variable polarization in time scales of days, with variable wavelength dependence in the polarization. These are the first reported polarimetric observations of S5 0716+714. Photometric observations show variability in similar time scales. We have also measured the photometric and polarimetric values for one calibration star in each blazar calibration sequence.
