Observations with a VLB Array II. The Sources 4C39.25, NRAO150, VRO42.11.01, 3C345, and 3C454.3,

Abstract

Three-antenna long baseline interferometry at 10.7 GHz is reported for NRAO150, 4C39.25, 3C345, VRO42.22.01, and 3C454.3 for several epochs between April, 1972 and February, 1974. Simple models for the source brightness distributions fit the observations and indicate that most of the radio emission comes from one or two components. Component separations range up to approximately 50 light years, and component sizes are on the order of 10 light years. Small variations in source structure have been observed.
