AN INVESTIGATION OF TAU A AND SGR A MILLIMETER WAVELENGTH RADIATION.
Abstract
The technique of investigating the position and flux density of 35 Gc and 70 Gc Tau A radiation and 35 Gc and 94 Gc Sgr A radiation are described. Tau A (35 Gc) and Sgr A (35 Gc) flux densities were 420 = 60 x 10 to the minus 26th power w/sq m/cps and 290 = 100 x 10 to the minus 26th power w/sq m/cps, respectively. The flux density of Tau A (70 Gc) interpreted from an antenna temperature signal to noise ratio of approximately 2 to 1 was 790 = 450 x 10 to the minus 26th power w/sq m/cps. Observations of 94 Gc of Sgr A, having a calculated antenna temperature standard deviation of 0.2C, revealed no source of radiation at the central position of Sgr A (35 Gc). The 35 Gc position of Tau A and Sgr A coincided, within the limits of the measuring accuracy = 3 (s) R. A. and =1' Dec., with lower frequency source positions. (Author)
