Results of a “grid search” for solutions in which (s, q) are held fixed on a grid of values, while the remaining five parameters are allowed to vary. The two “central-caustic” solutions that were previously discovered (Bond et al. 2017; Shvartzvald et al. 2017) were recovered, but two additional “resonant-caustic” solutions were also discovered. Full analysis of the combined data set (Table 2) rules out these solutions. The boundaries between the central-caustic and resonant-caustic regimes are indicated by dashed lines.
