Statistical insights into pulsar emission properties.

Publicly available dataset for further research.

Abstract

Over the past 13 years, the Parkes radio telescope has observed a large number of pulsars using digital filterbank backends with high time and frequency resolution and the capability for Stokes recording. Here we use archival data to present polarimetry data at an observing frequency of 1.4 GHz for 600 pulsars with spin-periods ranging from 0.036 to 8.5 s. We comment briefly on some of the statistical implications from the data and highlight the differences between pulsars with high and low spin-down energy. The dataset, images and table of properties for all 600 pulsars are made available in a public data archive maintained by the CSIRO.
