TESS transits of TOI-1130 b (upper two panels) and TOI-1130 c (lower panel) as used in the photodynamical modeling. Each transit is centred around the individual transit center times. The median PyTTV photodynamical model (see Sect. 3.5) is overplotted for both TOI-113 0 b and TOI-1130 c color-coded in salmon and blue, respectively. The light curves from Sector 27 are binned to 20-min (black points). Residuals are shown beneath each plot.
