Background-corrected XMM-Newton light curves of RX J1301.9+2747, extracted with time bins of 250 s in the 0.2 − 2 keV band as observed by the pn in light blue and by the MOS in dark blue. The epoch of observation name used in the text as explained in Table A.1 is marked in each panel. We number QPEs from number 0 (half-detected by the MOS in 2000) to number 33 (the last detected in 2022B) and mark a few of them with gray numbers.
