Notes.(1) ln 𝒵i–ln 𝒵i−1.(2) ln 𝒵i−1 − ln 𝒵best. The results are showed between the two approaches for the 3.4 days signal (alias of 1.4 days): a Keplerian (period of the alias at 3.4 days or period at 1.4 days, which is models with1.4) or a GP with the hyperparameters fixed at the retrieved values of the photometric analysis. The logarithm of the Bayes factor is reported for each pair of consecutive models and for each model with the best model (M4ccecJLgp1 for the 72 days GP and M3cccGLgp2 for the 1.4 days GP).
