Posterior TTVs of Kepler-419b, computed relative to a linear ephemeris computed using the median values of each epoch during Kepler observations (BJD_TDB = 2 454 959.358(23) + 69.728 8(21) × Epoch, where the errors are indicated in parentheses). A thousand random draws from the posterior distribution are used to estimatethe TTV median value and its uncertainty. In the upper panel the median TTV values are labelled with the corresponding epoch number (0 is the first transit observed by Kepler). In the lower panel, the posterior median transit timing value is subtracted to visualise the uncertainty of the distribution. The two sets of transit times derived in Dawson et al. (2014) are shown in light red (TAP) and light blue (GP), slightly offset in the x-direction for clarity. The median transit time was subtracted from each epoch to allow for comparison with our results.
