Phase-aligned γ-ray and radio light curves for PSR J0248+6021 obtained with the Fermi Large Area Telescope and the Nançay Radio Telescope. The bottom panels show the radio profiles at three frequencies used to build the ephemeris. The second panel from the bottom shows the degree of linear (red dashed) and circular polarizations (blue dotted), as well as the linear polarization position angle and a Rotating Vector Model (RVM) fit. The other panels show the phase-folded γ-ray data in different energy bands. Two rotations are shown for clarity.
