Notes. The limb darkening and photometric instrumental parameters can be found in Appendix F. The values assumed for the solar and planetary constants are the IAU 2015 Resolution B 3 values from (Prša et al. 2016). (a) The reduced barycentric Julian date in barycentric dynamical time (rBJDTDB), obtained by subtracting 2 400 000 from the BJDTDB. (b) Assuming a Bond albedo A = 0.
