Notes.Date, instrument, filter, and the nature of eclipse are given for each observation together with the photometric model function, red noise amplitude βred (as defined in Winn et al. 2008) and the rms of the binned (5 min) residuals. The notation p(ji) refers to a polynomial of degree i of parameter j, e.g. p(t2) denotes a polynomial of second degree with respect to time.
