FFP rate maps, in units of events per square degree per year, for events jointly detected by the Roman W146 filter and Euclid VIS filters (top two rows) and by 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 maps constrained only by the S/N criterion, while the right column shows the equivalent rate maps with all selection criteria present, including parallax and finite source effects.
