Data of TOI-2155 b from 13 TESS sectors. Panel (a) shows the detrended light curve from all TESS sectors using the biweight filter implemented in wotan with a window length of 0.5 days. Panel (b) presents a zoomed view of the raw PDCSAP flux from Sector 52. Panel (c) shows the detrended data of Sector 52. The detrended light curve was used in the global modeling of the TOI-2155 system.
