Pulse profiles of the 100 pulsars observed by LOFAR, showing from bottom to top LBA (green) and HBA (blue) profiles from LOFAR observations, 350 MHz (magenta) and 1400 MHz (red) profiles from WSRT and Lovell observations. We caution that the moding pulsars, for which only one mode of pulsation is represented by our observation, might not be the same for the profiles at different frequencies. The profile phase is zoomed-in on the interval 0.25–0.75 in all cases except for the pulsars with interpulses, where the full pulse phase is shown, and the profile is rotated by 0.25 in phase to shift the interpulse from phase 0. The star next to the band name indicates that the alignment for that band was made manually (see text for details).
