Caption: Figure 7.
Pulse profile of PSR J2021+4026 as observed by the XMM-Newton PN camera in 0.7–2.0 keV (see Figure 1 in Lin et al. 2013) and the best-fit simulated profile (solid curve) with the effects of gravitational light-bending incorporated. Error bars indicate the 1σ uncertainty. Two rotation cycles are shown for clarity.
