    • We showed in Ref. 17 that the growing structures were self-similar, regardless of time and quench depth. Thus, the prefactor must be the same for all of the quenches.

    • The theoretical curves for the three blend are nearly indistinguishable in the range of interest (ordinate difference in < 0.03). For simplicity, a single curve (the average between the three theoretical curves) is shown.
