Simulated dPA distributions compared with the dPA distribution of the FinAGN sample. The hatched histogram with errorbars denotes the FinAGN sample. The σ_j for three simulated distributions are listed in the figure. The K–S tests indicate a largest p_null corresponding to the smallest probability that the simulated and observed distributions are drawn from different populations when σ_j = 46°, which is marked with thick lines in the figure.
