TTVs are derived from Q1-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.

                Kepler KOI-5476 (KIC-8105719) 2-(or more?)-Planet System

Discussion:
For the only observed transiting planet, KOI-5476.01, in this system, a sinusoidal curve-fit of the (O-C) vs. Time data showed (Figure. below) a periodicity (P_ttv) of 338.95 ± 12.83 days; 341.02 days was observed in the Lomb-Scargle Periodogram of the same data.
