Histograms of spatial separation between PMPS pulsars and TeV source components from the HGPSC list. In the high-Ė pulsar sample (left), a clear correlation is seen as a peak at small squared angular distances, whereas the low-Ė associations,if present, are not significant beyond the expected rate of chance coincidences (right). The angular separation cut of θ < 0.5° applied in the preselection of PWN candidates (Sect. 3.2) is indicated by a dashed vertical line in the left panel.
