  We repeat our previous calculation of the spectrum distortion of massless
neutrinos in the early universe with a considerably better accuracy and
corrected for a missing numerical factor in one of the two ways of calculations
presented in hep-ph/9703315. Now both ways of calculations are in perfect
agreement and we essentially reproduce our old results presented in the
abstract of the paper and used in the calculations of light element abundances.
We disagree with the criticism of our calculations presented in
astro-ph/9712199.
