$a$: selected line for the APED-based {\it EM}~reconstruction.

$c$: selected line for the CHIANTI-based {\it EM}~reconstruction.

$\lambda_{\rm obs}$: measured wavelenght.

$\lambda_{\rm pred}$: theoretical wavelenght of the transition.
\par
$T_{\rm max}$: temperature of maximum emissivity in K.

For very weak lines, we have not calculated the errors on the total counts,
which are therefore labelled by the $\sim$ sign. In the CHIANTI database, 
the negative values of $\lambda_{\rm pred}$ mark the lines which are only
theoretically known.}
