It has been inserted so that energies of levels 16,17,18 could be determined from its value and the experimental energy difference measured by Kink et al 1997 from transitions involving each of these levels with level 11. The energy of levels 40,41,42 has then been determined from the energy difference measured by Kink et al 1997 for the transitions between levels 16-18 and 40-42. This means that the absolute energies of levels 16,17,18,40,41,42 are probably offset by a constant value, but their energy difference is experimentally correct. This allows CHIANTI to correctly calculate the transition wavelengths from these levels, to reproduce lines observed by SUMER in solar active and quiet spectra. % produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration % % E.
