Total average pulse profile of PSR B0950+08. The top panel shows the PA curve of the total average pulse profile with σ_ψ < 5°, along with the curve of PA ± 180°. To facilitate analysis of PA properties, the green curve representing the continuous variation of PA is plotted. The middle panel displays the average pulse profiles of total intensity I (solid black line), linear polarization L (solid red line) and circular polarization V (solid blue line), respectively. The zoom-in box shows the noise level region. The bottom panel presents a zoomed-in view of the region as outlined by the dashed box in the middle panel. The zoomed-in view of the circular polarization of the interpulse is shown within the rectangular box in the bottom panel.
