Abstract
BELOW 2,000 MHz the average pulse profile from the Vela pulsar (PSR 0833-45) shows a single peak with a sharp rise and a more gradual decay1. At higher frequencies a broader and more complex pulse is observed, evidently comprising two distinct components2,3. Observations at 1,400 and 4,830 MHz made with the Parkes 64-m telescope in November 1972 to clarify this frequency dependence can also be related to some γ-ray observations made by Albats et al.4 at the same time.
