  In the paper nucl-ex/0010009 by The Jefferson Lab F_pi Collaboration the new
results for the charged pion electromagnetic form factor are presented. The
approach given in our paper hep-ph/9811318, "On a possible estimation of the
constituent--quark parameters from Jefferson Lab experiments on the pion form
factor" makes it possible to estimate the mass of constituent quark from such
kind of experiment. Now this estimation gives M=0.21 GeV.
