Relationship between C IV ∥ distance, blueshift, EQW, and other empirical properties of the quasars in the subsamples investigated herein. Included are He II EQW, Γ, α _ox, Δα _ox, Δ(g − i), the C IV perpendicular distance, and redshift. The online interactive figure allows users to see all the combinations of data and select different subsets. At the top right are buttons that control the interaction with the online figures. These include (in order) tools to pan into and out of each panel (selected by default), zoom within a box, select subsets in a box, select subsets using a “lasso,” zoom using the scroll wheel, reset all the plots, and hover over a point to get more information. The hover tool is on by default and provides the SDSS ID and redshift for each object. The legends are also interactive. Clicking on a legend entry will toggle that data set on or off. All plots are initiated with only the “good” subsample (in green) as defined in Section 3.4.3. Data from Timlin et al. (2020a) and Lusso et al. (2020) (Section 2.1) are colored in purple. Data from the HST/Chandra, SDSS-RM, and Nardini et al. (2019) subsample are colored in orange, gold, and brown, respectively. Data points selected using the box or lasso tool are colored in pink (regardless of their parent sample). Only one panel at a time can be used for the select tool, and only data sets turned “on” in that panel will be selected (if turned on) in other panels.

(The data used to create this figure are available.)
