Simulated dPA distributions using the single component model compared with the observed dPA distribution. Left: simulated dPA distributions compared with the dPA distribution of the moreL+massive sample. Right: simulated dPA distributions compared with the dPA distribution of the lessL+massive sample. The hatched histograms with errorbars denote the observed distributions in each panel. The σ_j for the two simulated distributions are listed in the two panels. The simulated distribution corresponding to the largest p_null in each sample is highlighted in each panel.
