    • To avoid misunderstanding, we stress that the so-called "boson peak" is not a subject of the present discussion. Here we consider the exact zero-energy limit of the DOS.

    • Strictly speaking, this estimation can be performed only for the true DOS. It seems to be unjustified for the experimentally measured generalized DOS.

    • This is more appropriate than averaging of 〈v〉 values in Ref.12. Also, this gives better agreement with the measured DOS.
