The posterior distribution of the emcee chain of the six parameters fit in our model for collisional progenitors with radii ≥100 km and including a smoothed/plateau surface density. The model is fit with 50 walkers, 10,000 steps, and 1000 burn-in steps. The dashed lines indicate the 16th, 50th, and 84th percentiles.
