Statistical study of the pulse width distribution for radio pulsars

Pulse widths of standard pulse profiles for 262 pulsars were measured by using the Urumqi 25 m radio telescope at 1.54 GHz. For the simplest case of circular emission beam, we applied Monte Carlo simulations to the pulse width distribution. Different density functions of magnetic inclination angle α and observer angle ζ were considered. Using Kolmogorov-Smirnov tests, we derived the most probable distribution for α and ζ.
