J/AZh/87/238 Pulse profiles of radio pulsars at 102 and 111MHz (Malov+, 2010) ================================================================================ Average pulse profiles of radio pulsars at 102 and 111 MHz. Malov O.I., Malofeev V.M. =2010AZh....87..238M =2010ARep...54..210M ================================================================================ ADC_Keywords: Pulsars 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 20000m^2^.
