Note. The orbital periods are held fixed at 3.3601538 days (Van Eylen et al. 2021) and 11.38014 days (Mikal-Evans et al. 2023) for TOI-270 b and TOI-270 d, respectively. We use a stellar radius of 0.380 ± 0.008 R⊙ (Kaye et al. 2022) to estimate the planet radii. Also, note that the mid-transit time is given in units of BJD - 2400000.5 days.
