Caption: Figure 3.

IMF parameter: α vs. σe. Sample and marker layout are the same as in Figure 2, but instead using the mass-follows-light models for the z ∼2 sample from Mendel et al. (2020), which have a tighter ασ relation. Error ellipse in the bottom right represents the correlated errors for the 3.2 < z < 3.7 sample. Dotted lines are for a Chabrier and Salpeter IMF normalization. Blue solid line is the IMF–σe relation for the ATLAS3D+SLACS sample derived in Posacki et al. (2015), with blue shaded area representing the 1σ scatter.
