Statistical Properties of Pulsar CP 1919

THE pulsar CP 1919 (ref. 1) was observed at Parkes2 in March 1968 at a number of radio frequencies. On occasions the frequencies 85, 150, 150.9, 630 and 1,410 MHz were used simultaneously, with the 210 foot telescope tracking the source for some 4 h. The data have now been examined for statistical occurrence properties and a quantitative description of the source can be given. The statistics of pulse occurrence are of general interest because theories of emission (and pulse propagation) require these data. And anyway an observatory embarking on a programme of searching for such objects must know the statistical properties of pulse occurrence to aid in determining an observational programme.
