"Table 2" of "A measurement of alpha(s) from the scaling violation in e+ e- annihilation."

1996

alpha_s was evaluated from the scaling violation of the fragmentation func tions. The data from other experiments are used for the fitting procedure.

"Table 45" of "Energy dependence of event shapes and of alpha(s) at LEP-2."

1999

Three different schemes are used for evaluation of ALPHAS: (C=ALPHAS2) second alphas_s order, (C=NLLA) and (C=ALPHAS2+NLLA). See text of the paper for details. The second systematic (DSYS) error is the scale error.
