Relation between average recurrence time (t_recur) and average peak X-ray luminosity (top panel) or average eruption duration (t_dur, bottom panel) in QPE sources. The data is from Fig. 13 in A24. In the top panel the slope is consistent with zero (red dotted line), and thus with quantities being uncorrelated given the available data. In the bottom panel the slope is consistent with being linear in the log-log plane.
