Cumulative p-value distributions for the different metrics of lopsidedness applied to the isolated MATLAS (left) and ELVES (right) host environments. All p-values were calibrated from the comparison with 10⁵ isotropic satellite distributions, which have the same number of satellites and the same radial distribution as the dwarfs in the data. The dashed pink lines mark the significance threshold of 0.05. The orange boxes zoom in on significant regions. The diagonal black lines show the expected distribution from random isotropic systems.
