**Table 3:** Maximum-L parameters deduced from *XMM-Newton* observations of the TMC. Superscripts a) and b) refer to different observations of the same object; $T_{\rm exp}$ is the exposure time, and $N_{\rm cnt}$ is the observed number of counts (corresponding to ${\cal N}_{\rm src} + {\cal N}_{\rm bg}$ ). Errors outside brackets represent projections of the 68% likelihood surfaces (Fig. 11 inlets); errors in brackets are obtained from Monte-Carlo simulations (Sect. 6.3). Luminosities L_X refer to $N_{\rm H}$ = 0 and the energy band from 0.3 to 10 keV.
