Here we show the ranges of possible SNRs for each merger, by varying inclination and spin magnitude, for GM7 with CDM (left; purple) and SIDM-1 (right; green). Even with the most pessimistic SNR values, LISA would be able to detect such mergers, though note that these SNRs exclude the galactic foreground. We show the mean SNRs with dots. The error bars extend from the 5th percentiles to the 95th percentiles.
