Very Long Baseline Interferometer Observations of Taurus a and Other Sources at 121.6 MHz

VLBI observations with an antenna spacing of 92,000 A (2'(2 lobe separation) were made on a number of small-angular-diameter sources at a frequency of 121.6 MHz. Through positional and spectral coincidence, these observations confirm the physical association of the compact source in Tau A with the pulsar NP 0532; in the east-west direction, the two objects agree in position to an accuracy of 1011. The fluxes of the small-angular-diameter components of 3C 48, 3C 84, 3C 144, 3C 147, 3C 273, 3C 274, 3C 298, 3C 405, 3C 459, and 3C 461 are estimated.
