Fig. 2: Localization performance of the GET p-MINFLUX combination.

a Distributions of the distance z from graphene for exemplary molecules with a different dye position ranging from 12 to 30 nm analyzed with a fixed number of photons of N = 2000. b Exemplary 3D localization plots of a single fixed dye at a distance to graphene z of 16 nm with different number of photons, N, used to evaluate the precision. In this measurement, the SBR was 7. The individual localizations are shown in black and on the sides the corresponding projections. The red histogram is projection to xy. The orange histograms are the projection to xz and yz. The individual localizations are shown in black and on the sides the corresponding projections have a binning of 1 nm for xy and 0.2 nm for z. c Localization precision in xy and z as a function of the number of photons N for fixed dye molecules placed at different height. The gray stripe indicates the xy precision of MINFLUX in the corresponding experiments, the lines indicate the theoretical lower limit of precision
