Integrated pulse profiles of PSR B1451−68 at multiple observing bands spanning across 72 MHz–8.6 GHz. The profiles have been aligned by eye using the central component as a reference. Observations at lower frequencies (72–231 MHz) are obtained with the MWA, and those at higher frequencies (620–8612 MHz) are archival data from the Parkes/Murriyang (PKS) telescope. The profiles at the lowest and highest frequency bands are shown with 512 phase bins across the period, and those in between with 1024 phase bins.
