\begin{table}%T3
\caption{Optical and IR properties for all Cha~I~members and candidate members in the {\em XMM-Newton} FOV. The H$\alpha$ equivalent width ($W_{\rm H\alpha}$) is negative for emission. If more than one H$\alpha$ measurement is available for a given star we list the maximum and the minimum value observed. The T Tauri type given in Col.~6 of the same table is assigned on the basis of $W_{\rm H\alpha}$ using the criteria put forth by \protect\citey{Martin98.1}. Columns~7 and~8 represent the extinction and magnitude used to derive $L_{\rm bol}$; referring to the band given in Col.~9. The bolometric luminosity, effective temperature, age and mass have been computed as described in Sect.~\ref{subsect:lbol_age}. $L_{\rm bol}$ has been calculated for $d=160$~pc. We assign an age of $5 \times 10^5$~yr to objects on the birthline.}
