Probability distributions for the mass of (445) Edna based on its close encounter with (1764) Cogshall with the DR2 astrometry alone (red), the Earth-based astrometry alone (blue), and a combination of the two (green). We note that the densities on the upper x axis do not account for the uncertainty of the volume, which was computed from a volume-equivalent diameter of 86.30 km (Kretlow 2020). Due to the very long tail of the probability distribution in the DR2 case,a large portion of the distribution is beyond the scale of the figure. The frequency on the y axis is normalized such that the integral of each curve is unity.
