Caption: Figure 15.
Inferred mass distributions of various strongly modeled approaches compared to the fiducial mass model BROKEN POWER LAW + 2 PEAKS (gray shaded) and the B-SPLINE model (black dashed). The fiducial model from GWTC-3.0, POWER LAW + PEAK, is shown in orange, a broken power law with a single peak in blue, and a broken power law with three peaks in pink.
