a Time evolution of the mean squared error index (MSE) as a function of time. Frames at selected points are labeled from A to G. b Comparison of the A to G frames for different cooling rates (0.4 K/s to 0.01 K/s). The blue background (behind the E frames) points to the maximum in MSE for each data set. c Temperature dependence of the similarity index (MSE). The red arrow points to the peak corresponding to the maximum extension of the black pattern. Data are shifted downward to allow visualization. The blue dotted line shows the position of the critical temperature Tc.
