Specifically, we used A = 0.39 and b = 1.19 obtained from direct fitting of the modulus distance profiles with R=300 nm probe which we assume that the natural interphase affects less than other probes (denoted as "direct fitting") and compared the results to those obtained with A = 0.64 and b = 1.48 from the FEA simulation by Collinson, et al. (denoted as "FEA"). Tables and show the parameters obtained from fitting representative profiles in two different regions, i.e., reliable and inapplicable. The complete table can be found in SI.
