Three-year monitoring of a sample of flat-spectrum radio sources at 327 MHz.

GHOSH T., GOPAL-KRISHNA and RAO A.P.

Abstract (from CDS):

Result. of a 3-year monitoring programme at 327 MHz with the Ooty Synthesis Radio Telescope are presented. The majority of the sample consists of BL Lac objects, high-optical polarization quasars (HPQ) and low-optical polarization quasars (LPQ). In addition, a few known variable sources, GHz-peaked spectrum sources and compact doubles were also added. Including an additional set of 36 control and calibrator sources, a total of 82 sources were observed at roughly 3-month intervals for about 3 years. We find 19 variable and 6 possibly-variable sources. However, the observed variability in the BL Lac-HPQ-LPQ subsamples does not seem to be influenced by their optical properties.
