Absolute value of the relative period recovery error as a function of the base-10 logarithm Bayes factor, shown as density contours at the 25th and 75th percentile levels obtained through Gaussian kernel density estimation. The blue, orange, and green markers show the ideal, PTF and LSST baselines, respectively. The horizontal dashed red line shows a reference value |δP| = 0.15. The upper panel shows sinusoidal light curves, and the lower panel shows sawtooth light curves.
