Transit of HD 332231 b in Sector 14. Panels a and b compare the Sector 14 transit light curve (red points) with the phase-folded data from other sectors (grey points), zoomed in on ingress and egress to highlight discrepancies. The corresponding best-fitting models are shown as red and black/white lines. Panel c shows the raw instrumental flux around the Sector 14 transit, illustrating systematics affecting the measurements.
