Vetting procedure for TOI-942 b (green) and TOI-942 c (blue). Panel a: normalized light curve of TOI-942: green and blue arrows mark the position of the single transits of TOI-942 b and TOI-942 c, respectively. Panels b: comparison between the depths δ of the odd and even transits for the two exoplanets. Panel c: finding chart, centered on TOI-942 and based on the Gaia DR2 catalog: green and blue points represent the centroids computed analyzing the image obtained from the difference between theout- and in-of-transit stacked images; the red circle is the photometric aperture adopted in this work (see text and Nardiello et al. 2020 for details).
