\caption{Comparison of calculated BPRM absolute energies,
$E_{\rm c}$, with the observed ones, $E_{\rm o}$, for Fe~XX. $I_J$ is the level
index for calculated energy position in symmetry $J\pi$. The asterisk 
next to a $J$-value indicates that the term has incomplete set of 
observed fine structure levels.}
