Note: the first three columns indicate the indices (following the level 
ordering of  WB08),  the configuration and dominant 
$LSJ$. The following columns list the experimental level energies $E_{\rm exp}$ (cm$^{-1}$), 
 those obtained from the benchmark  calculation  $E_{\rm Bench.}$, those from NIST v.3 and those 
of the WB08 scattering target $E_{\rm WB08}$.
Values in parentheses indicate differences with the experimental  energies.
Only a selection of observed levels from the lower configurations,
producing the EUV~lines discussed here, are presented.
