The density posterior distributions for KOI-1300.01. The solid blue histogram shows the posterior density distribution from transit fitting for the primary star case. The solid red histogram shows the same for the secondary star case. The dashed blue and red histograms show the K. Sullivan et al. (2023) spectroscopic density distributions for the primary star and secondary star, respectively. Since the asterodensity posterior shows substantial overlap with the primary star but not the secondary star, we consider this planet to be unambiguously circumprimary.
