Notes. For the period and mid-transit time, values from Dalba et al. (2020) are used to construct prior distributions. <> symbols indicate fixed parameters. (a)This is an upper limit for the sky-projected stellar rotation velocity and cannot directly be compared to the values from Dalba et al. (2020), as they are derived from spectral analysis. (b) In fitting the transit light curve, Dalba et al. (2020) implement the quadratic limb darkening law, whereas the analytical RM model of Ohta et al. (2005) employs the linear formulation.
