Integrated Fermi-LAT γ-ray and Nançay radio profiles for the MSPs J0740+6620, J09311902, J14553330 and J17302304. Two full radio profiles are shown. For PSR J0740+6620 we display the LAT events recorded after MJD 55 800. Radio light curves all correspond to 1.4 GHz Nançay profiles recorded with the NUPPI backend, with 2048 bins per rotation except for PSR J09311902 for which the number of bins was reduced to 256 to improve the signal-to-noise ratio of the profile. The 30-bin γ-ray light curves were constructed by selecting Fermi-LAT photons found within 5° of the pulsars and with energies above 0.1 GeV. The photons were then weighted by the probability that they were emitted by the pulsars, as calculated based on spectral likelihood results.
