TSM, as defined in Kempton et al. (2018), for TOIs in multiplanet systems around bright M dwarfs (T eff < 4000 K and T mag < 11.5) with R p < 4 R as of 2022 July 7. TIC stars are sorted in decreasing order of second largest TSM value in the system. Color corresponds to host T mag and size corresponds to planet radius. The gray dashed line is the atmospheric follow-up threshold recommended by Guerrero et al. (2021) for sub-Neptunes. TOI 4342 is among the top 10 systems with multiple planets that are well suited for atmospheric characterization.
