Sample synthetic FRAP data generated using (1a), (1b) and parameters c = 0.031 μm/s, d = 0.061 μm2/s, β1 = 4e−13 s−1, and β2 = 0.007 s−1 were fit using our parameter estimation procedure. The recovered parameters are c = 0.029 μm/s, d = 0.06 μm2/s, β1 = 1e−12 s−1, and β2 = 0.007 s−1. To see this figure in color, go online.
