Light curve of the Crab pulsar at optical wavelength, 2.4−10 keV X-rays, 0.75−10 MeV, and 100−300 MeV gamma rays (from top to bottom). The light curve at 50−400 GeV is overlaid on each plot for comparison. The optical light curve was obtained with the MAGIC telescope using the central pixel of the camera (Lucarelli et al. 2008). The keV and MeV light curves are from Kuiper et al. (2001). The 100−300 MeV light curve was produced using the Fermi-LAT data. All light curves are zero-suppressed by estimating the background using the events in the phase range from 0.52 to 0.87.
