\caption{Parameters of the best-fit coronal models (with 1$\sigma$ errors) for the brightest candidate members. $T_{\rm av}$ is the EM-weighted logarithmic average temperature, defined as 
$\log T_{\rm av} = (EM_1~\log T_1+EM_2~\log T_2)/(EM_1+EM_2)$ 
\citep[see also][]{GuedelXEST2006}. 
The model flux (in the $0.3{-}10$~keV band ) is unabsorbed and the 
luminosity is calculated from it assuming $d=140$~pc.}\label{tab:sp_fit}
