Comparison of CRB of 2p-MINFLUX versus 1p-MINFLUX in xy-plane. a, b Comparison of CRB across xy-plane of (a) 2p-MINFLUX and (b) 1p-MINFLUX. Colormaps are rescaled into same dynamic range. CRB is calculated with N = 100, L = 50 nm, and SBR = 3. c Ratio of CRB of 1p-MINFLUX to 2p-MINFLUX in (a, b). Dotted lines represent directions for 1D profiles in (d). d 1D cut profiles of CRB ratio in (c). 4 angles (0, 20, 40, 60) are chosen considering symmetry. Three dotted lines represent r = 1\(\sigma\), 2\(\sigma\) and 3\(\sigma\). Scale bar: a–c 5 nm
