Same figure as Fig. 8, now including data from 2012 quiescence (black square) and an independent data set from the 2017 outburst (Paice et al. 2019, small black dots in the left panel). In the DRP-F_x plot (left panel) the quiescent F_x value was obtained with XMM-Newton 422 days after the DRP measurement (Armas Padilla et al. 2014b), which could affect its position on the diagram. The coefficients of a linear fit to all the data sets (excluding 2021 open markers) are shown in a text box.
