EE denotes choice of evolution equation: A for Aging, S for Slip. TH denotes the longest hold duration fit as part of this series. Fig no. denotes the figure number for the listed fits. V_i values are in $\mu \text{m}·{\text{s}}^{-1}$, and D_c are in μm.

^*denotes $a-b=-0.003$ constraint imposed on these fits.
