Notes. (a) There is a more recent and precise parallactic distance value from Gaia EDR3 at d = 14.642 ± 0.014 pc, but we kept the DR2 value for a better comparison with previous works. (b) Calculated from Kp = 2πaP−1 sinip using the parameters in this table. (c) T14 is the total transit duration between the fist (T1) and fourth (T4) contacts, and T12 is the duration of the ingress between the first and second contacts. (d)We corrected the system velocity (γ) sign from Charbonneau et al. (2009) as Kasper et al. (2020) remarked.
