High precision mass measurements in Psi and gamma families performed in 198
0-1984 at the VEPP-4 collider with OLYA and MD-1 detectors are revisited. T
he corrections for the new value of the electron mass are presented. The ef
fect of the updated radiative corrections has been calculated for the J/Psi
(1S) and Psi(2S) mass measurements. (C) 2000 Published by Elsevier Science
