Spin-down age vs. period in HBAs and at L-band for the pulsars whose profiles are not affected by scattering in HBAs. The colour (and symbol size) code for the number of peaks is white = 1, red = 2, green = 3, blue = 4, and violet >4. The histograms at the sides represent the distribution of these values as a function of spin-down age (right-most histogram) and of period (top-most histogram). From the plots no trend is visible in the number of peaks.
