Broad-band polarization observations of active compact radio sources

Abstract

Simultaneous multifrequency linear polarimetry data between 1.4 and 90 GHz were obtained for about 20 active, compact radio sources for six epochs between December 1977 and July 1980. A presentation is made of the total flux density results for fifth and sixth sessions, a summary of all polarization observations, and a description of the observational and analytical procedure. An inference is made that it is useful to decompose the observed polarizations from each source into a 'common' vector component, which appears to be related to the VLBI structural angle and a stochastic vector component which varies in both frequency and time.
