Table 3 Acquisition parameters for the various experimental configurations.

Camera	Analysis	Laser wavelength (nm)	Time per frame (ms)^a	No. of frames	Image pixel size (nm)	Map dimensions (Pixels)
EMCCD	FCS	488	2	50,000	240	46 × 46
Fig. 2	SRRF	488	200	500	24	460 × 460^b
EMCCD	FCS	561	2	50,000	240	120 × 56
Fig. 4	Diffusion law	561	2	50,000	240	114 × 56
	N&B	561	20	5,000	240	120 × 56
	SRRF	488	200	500	48	600 × 280^c

^aAcquisition time was 2 ms; longer times are reached by time binning of frames.
^b,cThe original image has a pixel size of 120 nm (b) and 240 nm (c) at 1 × 1 binning, respectively. During the SRRF analysis, virtual sub-pixels of sizes 24 nm (b) and 48 nm (c), respectively, are created.
