Overview of the vetting of TOI-4515 b. Panel a shows the normalized light curve obtained from the long-cadence FFIs: red and blue triangles indicate the position of odd and even transits, respectively. BTJD is the Barycentric TESS Julian date, the time stamp measured in BJD, but offset by 2457000.0, i.e., BTJD = BJD – 2457000.0. Panels b are the odd and even transits folded by using the period of 15.27 days: the transit depths are in agreement between the odd and even transits, excluding the eclipsing binary nature of the target. Panel c shows the X- and Y-normalized positions of the stars (stellar positions subtracted by the mean stellar position) on the image phase-folded with the period of the candidate exoplanet. Squares represent X and triangles Y. No correlation with the transits is observed. Panel d illustrates the phased long-cadence light curves obtained with different photometric apertures: the mean transit depth is the same within the errors, confirming that the transit signals are not due to contaminants.
