Notes.
Reported times are in Barycentric Julian Date calculated directly from UTC, without correction for leap seconds. Tc: reference epoch of mid transit that minimizes the correlation with the orbital period. T14: total transit duration, time between first to last contact; T12 = T34: ingress/egress time, time between first and second, or third and fourth contact.
Reciprocal of the half duration of the transit used as a jump parameter in our MCMC
analysis in place of
a/R⋆. It is related
to a/R⋆ by the
expression 
(Bakos et al. 2010).
Values for a quadratic law, adopted from the tabulations by Claret (2004) according to the spectroscopic (SPC) parameters listed in Table 5.
Planet equilibrium temperature averaged over the orbit, calculated assuming a Bond albedo of zero, and that flux is re-radiated from the full planet surface.
The Safronov number is given by 
(see Hansen & Barman 2007).
