Recurrence plots of pulsar profiles

Pulsars are rotating neutron stars that have an emission of electromagnetic radiations which is continuous but beamed. Therefore, an observer sees a pulse of radiation when the beam sweeps across his line-of-sight. Averaging over many pulses, a pulse profile specific for the observed pulsar is obtained. Here we propose the use of a recurrence plot for showing it. This plot can highlight specific behaviours in pulse profiles.
