TTVs are derived from Q0-Q17 Kepler data.  x-axes: “Observed Tc” (Mid-Transit Time): EXOFAST’s best-fits from Normalized PDCSAP_FLUX Kepler light flux vs. time (BJD_tdb - 2454900) data.  y-axes: “(O-C)”: difference between Observed Tc and the Calculated Tc from the graphically obtained linear ephemeris.

Figure: KOI-759.01, P = 32.63 days [Plot avg. error bars = ± 4.14 min., smaller than symbols]
TTV_maximum: 153.31 ± 21.42 days, Amp_ttv_maximum: 48.69 ± 2.47 min.
TTV_minimum: 770.53 ± 29.07 days, Amp_ttv_minimum: -65.87 ± 2.47 min.
TTV_maximum: 1387.75 ± 41.82 days, Amp_ttv_maximum: 48.69 ± 2.47 min.
P_ttv: 1234.44 ± 32.15 days.
Amp_ttv: 114.56 ± 3.49 minutes.
Lomb-Scargle periodogram, periodicity (P_ttv): 1324.15 days; Power: 15.32; FAP: 0.
Linear ephemeris (this work): Tc = 32.62873081(Tc#) + 127.10400554

KOI-759.02, P = 91.77 days
Two relatively weak, low-credibility periodicities were discerned in the Lomb-Scargle periodogram:
380.56 days; Power: 2.70; FAP: 0.099
697.01 days; Power: 1.63; FAP: 0.503
and clearly, even if valid, neither was anti-correlated to the relatively strong TTV of 759.01.
Linear ephemeris (this work): Tc = 91.77354303(Tc#) + 126.83594637
