Best fit to the 17–24 Å RGS spectrum (in the observed frame) of NGC 3783 from 11 December 2016. The best-fit model with contributions from all emission components is shown in purple. Contributions from individual emission components are color-coded, with red and blue for narrow emission features and green for broad emission features. The orange solid line is a calculation using the best-fit parameters obtained from the time-averaged archival spectrum for all three emission components. Due to the obscuration effect, the broad emission component (EM 3) appears to be weaker in December 2016.
