Correlations using the “characteristic” X-ray luminosity LX, char. Left: LX, char vs. M. The cross indicates the typical uncertainties. The LX, charM relation doesnot differ significantly from the LXM relation (see Fig. 1). Right: same plot as in Fig. 2, but corrected for flaring activity, as described in Sect. 3.4. The anticorrelation is stronger and more significant.
