KIC 9472174: O−C diagrams calculated from: (a) SC and LC data (violet and green dots, respectively), and (b) data prewhitened from pulsations (black dots are the O−C from the single-template fit to the SC data; red dots represent the O−C from the seven-period template fit to the SC+LC data). The diagrams were shifted vertically to avoid overlapping. Bottom panel (c): O−C diagram from a seven-period template fit prewhitened for the 1430 day period. The black line shows a 416 day sinusoidal fit to the O−C from Fig. 3 of Baran et al. (2015).
