J/AZh/71/717     Polarimetric Observations of BL Lac     (Gagen-Torn+ 1994)

Polarimetric Observations of BL Lac Gagen-Torn V.A., Marchenko S.G., Yurchenko A.V., Yakovleva V.A. <Astron. Zh. 71, 717 (1994)> =1994AZh....71..717G
ADC_Keywords: BL Lac objects ; Polarization Description: This paper continues publications that report the results of photoelectric polarization measurements of the blazar BL Lac. Earlier, we published observational data obtained over the period 1969-1982 (Hagen-Torn et al., 1984AZh....61..925H). Here, we discuss the observations over the period 1983-1991.
