**: Used for abundances only.

Note: For He-like ions, the line flux includes the resonant line only. For H-like ions the flux includes both lines of the Ly $\alpha$ doublet. For Fe the flux includes all the transitions of the ion within 0.03 Å of the given wavelength. Flux errors include 10% instrument calibration error.
