Notes. The signal-to-noise ratio on the lines is estimated either from the pipeline error spectrum, or by repeating the fit on 300 realisations of the spectra generated via randomly bootstrapping (with replacement) over the 186, 42, and 114 individual integrations available for the PRISM, G140M, and G395M configurations, respectively. 3σ upper limits are reported for non-detections.
N IV] λ1483,1486, C IV λλ1549,1551, O III] λλ1661,1666, [O II] λλ3726,3729 are modelled as unresolved doublets in the PRISM spectrum.
When including the N IV] λ1486Gaussian component in the PRISM fitting (see Sect. 2.2.1 for details).
