Asymmetry measures for the observed LAT LCs compared to a subset of synthetic OU LCs. The bins are set by the Bayesian block algorithm. The dashed and transparent bins are set to 0.25 and are plotted for convenience to show a “classical” histogram. The Bayesian binning shows that the asymmetry measures for both data sets basically are present in a range between (−1,1) with the same probability. Top: three- block HOP group omitted; bottom: four-block HOP groups omitted.
