fIT provided by DIAMONDS for three different observation lengths for KIC 9903915. Upper row: full background model, lower row: noise only model. Different observation lengths are split into three columns: first column: result for the full 1400 day light curve, second: for 109.6 days and third: for 27.4 days. We find strong evidence for all three observation lengths: log O = 990.53 for 1400 days, and log O = 75.42 and log O = 13.86 for 27 days. Even at 27 days we are still above the threshold of log O = 5 for strong evidence.
