Best-fit parameters. Height (top panel), L_transf/L_disc (middle panel), and photon index (bottom panel). The grey shaded area shows the 1σ confidence interval, which we computed by repeating the fitting procedure 100 times, each time resampling the X-ray light curve from Gaussian distributions centred on the measured values with standard deviations equal to their error bar. For computational efficiency, these fits were performed using a coarser parameter grid (i.e. 10 values per parameter instead of 20). The red triangle points show the results of K24.
