Radio Observations of Five Pulsars

Abstract

WE have reported¹ measurements of the characteristic pulse shapes, dispersions and spectra of the four pulsars, CP 0834, CP 0950, CP 1133 and CP 1919, discovered by Dr Hewish and his group at Cambridge². The 250 foot telescope at Jodrell Bank has been used to observe the five new pulsars CP 0328, CP 0808, HP 1506, PSR 1749–28 and PSR 2045–16 reported by Cole and Pilkington³, Huguenin et al.⁴, and Turtle and Vaughan⁵. We describe here measurements of the positions, periods, dispersions and pulse shapes obtained at frequencies of 151 MHz, 408 MHz and 610 MHz. The observational techniques used have been described before⁶.
