The 80 targets ranked by ESM15 and the bolometric priority metric (left), by ESM15 and the cumulative XUV priority metric (center), and by the two priority metrics. The targets are chosen from the DDT “Targets Under Consideration” list. The vertical and horizontal lines indicate quartiles along each dimension. The color indicates the effective temperature of the host star, with red (blue) markers corresponding to targets orbiting early- (late-) M dwarfs. The targets are scaled by their ESM15. The factor of ∼3 disagreement in cumulative XUV between the scaling in K. J. Zahnle & D. C. Catling (2017) and age-based calculations (B. Park Coy et al. 2024), propagated to the priority metric, is shown as the modeling uncertainty in the right panel; this should not be construed as a 1σ uncertainty.
