23. Although the approximation becomes better as longer coarsening lengths are chosen, a proper choice of the coarse-graining scale as described in the text is indeed a key to correctly reproduce the β-relaxation as well as the α-relaxation. If a longer coarsening scale is employed to capture the latter process as was done by C. Dasgupta and O. T. Valls: Phys. Rev. E 53 (1996) 2603, the nonlinear feedback mechanism of density fluctuations giving rise to the former process is completely lost.
