TESS light curve SAP (top panel) and PDCSAP flux (middle panel) with original cadence (blue) and binned to 10 minutes (orange). The bottom panel shows phase folds according to planetary periods and mid-transit times derived by Rodriguez et al. (2018) for planet b (left), planet c (middle), and planet d (right). The red line presents a transit model based on parameters from Rodriguez et al. (2018) for illustrative purpose.
