Correlation plots of PSR J1926+0737. Panel a: Auto-correlation curves of the MP and the IP intensities, which reveal any periodicities in the pulse intensities. The plots are zoomed-in to the y-range of −0.1 to 0.2. Panel b: Cross-correlation between the MP and the IP single-pulse intensities and its error bars in black line, and the correlation when reversing the order of the single pulses in grey dashed line. The corresponding correlation of the off-pulse regions is in red. Panel c: Correlation plots computed using the running averaged intensities of the MP and the IP, with the Fast full sequence in black, and the MeerKAT full sequence in blue, respectively.
