Notes: A is the elemental abundance and EM the emission measure. $T_{\rm m}$ and s are the temperature of maximum emissivity of the line and the corresponding line emissivity factor. $\lambda_0$ is the theoretical wavelength from Kelly (1987). Fluxes are given in units 10-6 photons cm-2 s-1. $A \times EM$ is given in 10 $^{52}~{\rm cm}^{-3}$. The error in $A \times EM$ includes the relative error in the flux values and a 15% error in the values for transition probabilities, imbedded in ``s''.
