Table 4:

a) SERTS/EIS observation (Keenan et al. 2000; Brown et al. 2008) for a solar active region along with predictions (for the line emissivity $\epsilon $ and intensity I, based upon the observed line flux at 258.37 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.
