The probability PDFs of a, e, i, and H from our modified base model with the extended magnitude range (15 < H < 28; blue lines) is compared to the CSS NEO detections (red lines). The shaded areas are 1σ (bold gray), 2σ (medium), and 3σ (light gray) envelopes. We used the best-fit solution (the one with the maximum likelihood) from the modified base model and generated 30,000 random samples with 4412 NEOs each (the sample size identical to the number of CSS’s NEOs in the model domain; 15 < H < 28). The samples were biased and binned. We identified envelopes containing 68.3% (1σ), 95.5% (2σ), and 99.7% (3σ) of samples and plotted them here.
