Corner plot for the medians of the posterior PDFs of various QPE parameters of RX J1301.9+2747. The quantities plotted for each QPE are: the bolometric luminosity at the QPE peak (10⁴² erg s⁻¹); the temperature at the QPE peak (keV); the QPE duration (m); the QPE total emitted energy (10⁴⁵ erg); and the time preceding each QPE (h). Strong QPEs are plotted with filled circles, weak QPEs with open squares. Error bars for weak QPEs have been omitted for clarity. A couple of correlation coefficients between the parameters is reported in the lower right corner of each plot: strong QPEs only on top, and both strong and weak QPEs in the gray boxes below.
