Notes. The columns list the time stamp in BJDTDB (Eastman et al. 2010) minus a constant, the O–C value and its error σ(O – C) as evaluated by the pipeline described in Section 3, the best-fit model with a linear baseline (O – C)lin (Eq. (8)) and its residuals, and the best-fit model with a quadratic baseline (O – C)quad (Eq. (7)) and its residuals. The unit of all columns except for the first one is seconds.
