Cumulative rate fraction for a maximum H-band magnitude and minimum 〈µ_rel〉 is shown in both the Roman W146 and Euclid VIS filters (top two rows) and the NISP filter (bottom two rows). Rows 1 and 3 use the Mróz model of ten Earth-mass FFPs per main sequence star, while rows 2 and 4 use the Sumi model of two Jupiter-mass FFPs per main sequence star. The left column shows rate fraction constrained only by the S/N criterion, while the right column shows the equivalent rate fraction with all selection criteria present, including parallax and finite source effects. The 0.5, 0.75, and 0.9 contours are shown for reference.
