Table 1
Priors on TRAPPIST-1 stellar parameters and TRAPPIST-1h orbital parameters.
| Parameter | Unit | Value |
|---|---|---|
| R* | R⊙ | N(0.1192, 0.0013) |
| M* | M⊙ | N(0.0898, 0.0023) |
| P | days | N(18.7672745, 0.00001876) |
| b | - | N(0.448, 0.054) |
| T0 | BJD tdb | U(t0, tf) |
Notes. R* and M* are respectively the stellar radius and mass with prior distributions from Agol et al. (2021). P and b are TRAPPIST-1h orbital period and impact parameters taken from Ducrot et al. (2020). T0 is the transit mid-time, and the transit depth is set to an uninformative uniform prior. U(a, b) denotes a uniform distribution bounded by (a, b), and N(µ, σ) a normal distribution of variance σ2 centered on µ. t0 and tf correspond to the times of the first and last exposures of a given visit.
