Inclination vs. perihelion for the classical KBOs and scattered KBOs in our sample (filled circles) and all published data (no Plutinos; open circles). For illustrative purposes, a linear least‐squares fit has been plotted for points with perihelion greater than 34 AU (solid line). The gray bars represent the constant q (vertical bar) and constant i (horizontal bar) subsamples detailed in Fig. 3.
