Quasar systemic redshift from the SDSS catalog and, in brackets, from the peak of the [C III] complex (i.e., [C III] is a doublet 1906.7, 1908.7 Å; and [Si III]λ1892 could be blended), after correcting for the expected shift (Shen et al. 2016). The intrinsic uncertainty on this correction is ∼233 km s−1 and dominates the error budget (Δz ≈ 0.003).
i magnitude extracted from our data using the SDSS filter transmission curve and a circular aperture with a radius of 2″. The SDSS i magnitudes for the two quasars are iQSO1 = 21.50 ± 0.08 and iQSO2 = 22.05 ± 0.12.
3× rms at 1.4 GHz from the Very Large Array survey: Faint Images of the Radio Sky at Twenty-Centimeters (VLA FIRST; Becker et al. 1994).
