Simultaneous optical and infrared polarization measurements of blazars
(1986)
The authors present measurements of the polarization and flux of a sample of 28 blazars (21 BL Lacs and 7 OVV quasars) at optical and near-infrared wavelengths, with repeated observations for some objects. As in earlier ...
Coordinated multisite observations of the variability of BL Lac
(1985)
The authors present the results of multisite observations of the optical polarization of BL Lac, together with some flux measurements, at a time when BL Lac was relatively faint. The level of polarization varies in a manner ...
