Multi-wavelength pulse profile of PSR J0437−4715 as observed in the radio by Parkes at 1.4 GHz (red line), in soft X-rays by NICER (0.3−3.0 keV, green line), and in γ-rays by Fermi/LAT (black line). Note that the zero line of the NICER data is arbitrary since, technically, the pulsed emission lies on top of an un-pulsed pulsar emission plus background emission (all origins combined). We note that this is also true for the radio data, for which the profile baseline has been subtracted to lie at zero.
