Notes. TIC ID and Gaia DR3 ID refer to the TESS Input Catalog and Gaia Data Release 3 identifiers of the object, respectively, N is the number of data points after cleaning the light curve, δT is the total length of the data sets including gaps, and Sect. is the serial number of the sector(s) in which the star was observed. US and S denote that we used the ultrashort- or short-cadence-mode observations, respectively. The start time in BJD is the time of the first data point in the data set. The CROWDSAP keyword represents the ratio of the target flux to the total flux in the TESS aperture. We note that here we list the CROWDSAP value from the first TESS run, even when data from other sectors are available.
(*)We corrected the CROWDSAP value from 0.08, which corresponds to a background star, as detailed in Sect. 3.9.
