Table 3: Energy levels in Rydbergs for the 14 LS target states included in the calculation, relative to the S V 2p⁶3s² ¹S $^{\rm e}$ ground state. Values are shown for the experimental data of NIST along with the values obtained from the current calculation, as well as data from the calculations of the Opacity Project (Butler et al. 1992)[OP], Christensen et al.(1986)[C et al.] and Dufton & Kingston (1984)[D&K]. The differences between the observed values of NIST and the data from each of the three calculations are given in parentheses.
