Notes. 1. Gaia Collaboration (2016) 2. Gaia Collaboration (2023) 3. Cutri et al. (2003) 4. Mancini et al. (2018) 5. This work (TEATRO) 6. Kokori et al. (2022) 7. This work (CASCADe). d is the distance. The limb-darkening coefficients u1, u2 are in the NIRSpec G395M bandpass. b is the impact parameter. a/R★ was fixed to the value from Mancini et al. (2018) for TEATRO and was a free parameter for CASCADe, which causes some differences in the derived parameters. The uncertainties reported for TEATRO and CASCADe are only those from our fits, they do not take into account the uncertainties of the fixed parameters. The parameters from CASCADe were obtained from an optimisation process that does not provide uncertainties (except for the transit depth), but are consistent with Mancini et al. (2018). The CASCADe fit used the mid-transit time from TEATRO.
