Best-fit results of the X-ray photoionized emitter in the time-averaged spectra of NGC 3783. The emission measure (E.M.) is calculated based on the best-fit parameters.

Notes. Parameters followed by (f) are fixed in the fit. The 2000–2013 MEG (6–17 Å) data and the 2000–2001 RGS (7–37 Å) data are fitted simultaneously (Sect. 3), but constraints are obtained mainly from the 2000–2001 RGS data since it covers all the emission features from Ne, O, N, and C. Statistical uncertainties are quoted at the 68.3% confidence level.
