Comparison of the inner planet models against three different data sets. A. An inner planet model applied to the full data set. B. Same as A, but ignoring the best epoch (2021). C. Same as A, but after subtracting the best fitting model found by A from the 2021 epoch. The four panels show orbits drawn from the posterior, posterior density of planet position calculated at the 2021 epoch, median photometry if the planet were at that position in 2021, and photometric accuracy at those positions, i.e., the S/N of a planet if it were on an orbit that would pass through that pixel in 2021. Pixels are left blank where there are only a negligible number of samples.
