The overlay shows the stopping depth distribution of muons with an energy of 19 keV, corresponding to an average stopping depth of 54 nm (x = −2 nm in Fig. 2). At this energy roughly half of the muons come to rest in the Nb layer, probing its first 30–35 nm, yet the integrated flux expulsion is close to zero.
