Table B.1

Photometric baseline models, residual RMS, and error scaling factors βw and βr for each transit light curve used in our global transit analysis (see Sect. 4.1). For the baseline function, o is a simple constant (to account for any out-of-transit flux offset), sp(r) is a cubic spline against the spacecraft roll angle r, and p(α) denotes a first-order polynomial function of the parameter α, with α that can be t = time, b = background, a = airmass, x and y = x- and y- position of the target on the detector, or ttt = telescope tube temperature. Epochs are relative to the updated mean transit ephemerides given in Tables 3 (planets b, c, and d) and 4 (planets e, f, and g).
