Measurements of the Pulsed Radio Source CP 1919 between 85 and 2,700 MHz
The pulsed radio sources1,2 emit energy almost simultaneously over a wide frequency band3. Pulses from the source at 19h 19m 37s, + 21°47′02″ (epoch 1950) have been received with the Australian 210 ft telescope at frequencies of 85, 150, 630, 1,410 and 2,700 MHz. This report covers measurements of the spectrum of the pulses, the characteristics of the intensity variations at different frequencies, and observations of the structure and polarization of the pulses. A previous communication4 discussed measurements of the period of the pulses and of the dispersion between 85 and 1,410 MHz.
