Notes:  {$i-j$ are level indices, $\lambda_{\rm obs}$ the observed 
wavelength with the 
 uncertainty (last digit) and the source. 
 (bl) indicates the presence of a blend, mr in medium-resolution 
spectra.
ID indicates the original identification
 (N is a new  identification proposed here), while 
 Diff. ID indicates a differing identification.
