The Eta Carinae Nebula and Centaurus A Near 1400mc/s. I. Observations

Observations of two strong southern radio sources, the Eta Carinae Nebula (NGC 3372) and Centaurus A (13S4A), at a frequency near 1400 Mc/s, are described. The observations were made with a 36 ft transit-mounted paraboloidal aerial and a 21 cm hydrogen-line receiver modified for the reception of con...

Description
Summary:Observations of two strong southern radio sources, the Eta Carinae Nebula (NGC 3372) and Centaurus A (13S4A), at a frequency near 1400 Mc/s, are described. The observations were made with a 36 ft transit-mounted paraboloidal aerial and a 21 cm hydrogen-line receiver modified for the reception of continuum radiation. The flux density of the Eta Carinae Nebula near 1400Mc/sis5 82 X 10-24Wm-2 (c/s)-\ with an estimated uncertainty of less than 20 per cent. This source appears to be fairly symmetrical, with a strong central condensation.
