Distribution of the Bayes factors for the 10⁴ noise-only light curves for the PTF using the periodic kernel and cosine kernel (blue and dark blue distributions) and ideal using the periodic kernel and cosine kernel (orange and red distributions) baselines, and the 10³ noise-only light curves for the LSST (green distribution) baseline found by analysing the light curves with the generic periodic kernel. The vertical lines refer to the Bayes factor threshold identified for a fair comparison with the LSP analysis discussed in more detail in Section 3.5.
