Phase-folded lightcurve for TIC 391461666. Upper panels: fold on two possible periods of the second EB, PB = 351.8/N days: PB = 39.09 days, (i.e., N = 9, upper left), and PB = 19.54 days (i.e., N = 18, upper right). Both provide a convincing case for binary B and thus a potential true period. Lower panels: same as upper panes, but for two values of N for which PB = 351.8/N days can be ruled out from the available data: N = 8 (lower left) and N = 17 (lower right).
