Fig. 1


The wavelength differences between present FAC2 calculations and HFR1 results, as well as results from relativistic Z-expansion method. The two sets of differences are plotted versus FAC2 wavelengths in Å for Si xi. Squares: HFR1 (Palmeri et al. 2008). Cross: relativistic Z-expansion method (Boiko et al. 1979).
