\tablefoot {The columns indicate: 1) the  indices corresponding to Table~\ref{tab:levels}; 2)~the  wavelengths calculated from the experimental energies~$E_{\rm exp}$; 3)~the observed  wavelengths~$\lambda_{\rm obs}$. The original source is indicated. N~refers to a new measurement presented here. For lines above 2000~\AA,  air wavelengths are indicated. bl,~sbl indicate  that a line is  blended or is a self-blend. 
u~indicates blending with an unidentified line. 
Columns~4) and 5) indicate some of the previous identifications consistent or not with the present ones (with  observed  wavelengths in~\AA). N~in Col.~4 indicates a new identification.}
