Map of Bayes factors for 1500 unevenly sampled realisations of UBHD light curves with a ten-year baseline. The colour scale represents the base-10 logarithm of the Bayes factor, while the axes show the ratio of the model parameters between the two light curves. The red square, diamond, triangle and circle correspond to the light curves used to compute the periodograms shown in panels a,b,c, and d, respectively, in Figures 6 and B.1.
