Output from the centroids module for TOI-1243 b in TESS Sector 60 (top), for TOI-4529 b in TESS Sector 42 (middle), and for TOI-5388 b in TESS Sector 21 (bottom). The dashed white lines outline the aperture mask for LC extraction. A star symbol indicates the cataloged position of the target, while a purple triangle shows the average out-of-transit photocenter. Individual photocenters are marked by small red dots, and the large red circle denotes the overall difference image photocenter. The panels show: upper left – difference image; upper right – average out-of-transit image; lower left – average in-transit image; lower right – S/N of the mean difference image. A color bar indicates the number of electrons/sec for each case mentioned. The difference image reveals a centroid offset without artifacts slightly contaminated by the presence of a nearby source.
