Table 3: Measured RGS line fluxesa of $\sigma $ Ori AB. $\log T_{\rm max}$indicates the maximum temperature (K) of formation of the line (unweighted by the EMD). "Ratio'' is $\log (F_{\rm obs}/F_{\rm pred})$ for each line. Blends amounting to more than 5% of the total flux for each line are indicated.
