Cross-correlation factor plotted as (1–C) on the y axis, where C represents the correlation between the template profile and sub-integrated averaged profiles. The x axis shows the number of pulse rotations on a logarithmic scale. A lower (1–C) value indicates a higher similarity with the template. The red line denotes the best-fit power-law trend. The exponent for the power law fit is −0.42 ± 0.03.
