Histograms of the expansion factors ffit, Eq. (16), computed (a and c) at the front, and (b and d) at the rear MC boundaries. They are the extreme values of f(t) across MCs. ffit values are derived from linear (top) and quadratic (bottom) fits of the observed velocities (similar results are obtained with the model fit).
