Top : transit-timing variation for the TESS mission. The open blue circles represent each transit time subtracted from the best-fitting linear ephemeris. The pipelines and sectors are labelled at the top. The abscissa was zoomed for better visualisation while avoiding the large gaps in the time domain. Centre : transit-duration variation. The dotted blue and shaded light blue regions represent the transit duration median and its 1σ confidence interval. Bottom : transit depth variation. The colour scheme is the same as above.
