XIE G.Z., LI K.H., ZHANG Y.H., LIU F.K., FAN J.H. and WANG J.C.
Abstract (from CDS):
The optical (BVRI) and infrared monitoring data covering 2 years for 10 radio-selected BL Lac objects and the simutaneous observations of optical and infrared for BL Lac and 3C 66A are presented here. Seven sources exhibit short time-scale variability, and two sources exhibit medium time-scale variability. A test of radiation models is discussed.
