Measurements of the Pulse Shape and Spectra of the Pulsating Radio Sources

  • A. G. Lyne
  • B. J. Rickett


Following the observations1,2 of the pulsating radio source CP 1919 at α = 19h19m, δ = 21° 47′, the three other sources reported by Hewish et al. 1 have been studied with the 250 ft. telescope at Jodrell Bank. Simultaneous observations have been made on frequencies of 151 MHz, 408 MHz and 922 or 1,412 MHz, to obtain the spectrum of the radio emission and to compare the shapes of the pulses emitted by the four known sources.
