Differential histograms of all three absolute magnitude H distributions used in modeling the NT population in this work. In all cases, the solid line represents the analytical model for the distribution, while the histograms are the uniformly sampled N_NT objects from that model. The shaded regions in all cases represent the region beyond the LSST’s nominal single-visit detection threshold (H_r ≈ 10) for an object at Neptune’s orbit. Represented here are (left panel) the single-component model, (middle) the two-component model, and (right) the rolling power-law model. Note that the single- and two-component models have a logarithmic y-axis scale, while the rolling power-law model is linear.
