Table 5:

a) SUMER observation for the quiet sun (Curdt et al. 2004) along with predictions (for the line emissivity $\epsilon $ and intensity I, based upon the observed line flux at 638.92 Å) at $T_{\rm e}=10^{6.1}$ K and $n_{\rm e}=1.6$ $\times $ 109 cm-3. The ``-'' tag in the $\lambda $-columns denotes those wavelengths corrected by experimental energies.
