Webprofiles to the lowest frequency 102 MHz where such observations have been performed so far. A comparative analysis of the profile frequency dependence indicates that the frequency dependence of a profile width of millisecond pulsars is much weaker than what is typically observed for normal pulsars (Kuzmin & Losovsky 1999b, 2000).
