Notes.Fixed parameters: Teff = 7430 ± 100, [M/H]= 0.1 ± 0.2, P = 1.2198709 days, Tc = 2 452 950.6724 [HJD], e = 0 (circular orbit is used, based on the occultation data of Smith et al. 2011 and Deming et al. 2012 – see however de Mooij et al. 2013), T12 = T34, i.e., ingress duration is assumed to be equal to the transit duration. The central hump phase of the light curve (see Fig. 10) was omitted in the global parameter determination.
