Abstract:
Average profiles for 180, mostly faint, pulsars at 102 and 111MHz are
presented. Pulse shapes have been obtained for the first time for most
of the faint pulsars (about 50% of the total sample). A comparison
with high-frequency data (mostly at 234, 408, 610, 925, and 1408MHz)
demonstrates appreciable changes in the profile width and shape with
frequency. For most pulsars, the number of components is preserved,
but the intensities of individual components can change. As a rule,
the profile width increases with decreasing frequency. The possible
generation of emission at the cyclotron frequencies is considered.
Description:
We surveyed more than 200 (mostly faint) radio pulsars from 1994
to 2006 using the Large Phased Array radio telescope, which has an
effective area of about 20000m2.
