^aGPCR membrane diffusion coefficient computed from slope of first two MSD(τ) points (first phase).

^bGPCR membrane diffusion coefficient computed from slope of the second phase of the MSD(τ) plot.

^cGPCR membrane diffusion coefficient found by fitting MSD(τ) with corralled random walk simulation. This represents the D_m that is least affected by corral confinement.

^dProbability of a GPCR crossing a corral boundary upon encountering the boundary, found by fitting MSD(τ) with corralled random walk simulation.

^eMean length of corral in the axial direction, computed from y-intercept of the linear regression of the second phase of the MSD(τ) plot.

^fMean residence time for a GPCR within a corral, found by fitting MSD(τ) with corralled random walk simulation.
