Left: the C IV parameter space of our subset of Timlin et al. (2020a) quasars with the C IV EQWs and blueshifts from that same paper shown as the gray circles, and the ICA-generated C IV parameters colored by the C IV ∥ distance. The best-fit line to the ICA-generated C IV EQW and C IV blueshift space is shown as the solid black curve. Right: same as the left panel, but colored by the C IV ⊥ distance.
