\tablefoot {\tablefoottext{a}{Four high-$L_{\rm [Ne~II]}$ objects have not been considered for these correlations, namely T~Tau S, DG~Tau, EC~82, and Sz~102
(see text and figures for details). Sz~102 has not been considered in any of the correlations that involve $L_{\rm X}$.}\\
The number of points (``\# points'') includes upper limits, detailed in the column ``\# upper limits''.\\
$L_{\rm X}$ refers to $L_{\rm X, 0.3{-}10, unabs}$. $P$ is the probability that the correlation is obtained by chance. $P$ values
up to~5\% and between~5\% and~10\%  are printed in boldface and italics, respectively.  }\vspace*{-1.5mm}
