\caption{\label{m_estim}Initial mass estimate (in solar units) from evolutionary diagrams. The second and third column give estimates based respectively on the $X$(H$)-L$ and HR~diagram. The errors take into account uncertainties on \teff\ and \lL. Tracks with $Z = 0.2~Z_{\odot}$ from \citet{mm05} are used.}
