GP analysis of the TESS photometry time series. The top panel shows the TESS data obtained in Sectors 16 and 17, and the bottom panel shows the data obtained in Sector 24. Black hollow circles show the TESS photometry in its original sampling, and the black points show the binned data, where each bin is calculated by the weighted mean within windows of 0.1 day. The orange line and shaded region show the best-fit GP model (multiplied by the transit model) and its uncertainty.
