Fig. 4
Synthetic ACIS-S spectra with high Si abundance. Black: synthetic ACIS-S spectrum of a CIE plasma with abundance of all elements set to 3, with the exception of Si abundance set to 300; kT = 0.8 keV and EM = 1.5 × 1055 cm−3. Red solid: same spectrum but with the Si line emission subtracted, but Si contributions to the FF and FB continuum are still included.
