In an earlier paper [1], the background for K-e3 was over estimated due to an erroneous calculation of the electron identification efficiency. The correct ratios of the partial widths involving this channel are R-Ke3/K2 pi = 0.2470 +/- 0.0009 (stat) +/- 0.0004 (syst) and R-K mu 3/Ke3 = 0.663 +/- 0.003 (stat) +/- 0.001 (syst). Assuming the PDG value [2] for the K-2 pi branching ratio, the measured branching fraction of Br (K-e3) continues to exceed the current PDG value [2]. The extracted value of |V-us|f(+)(0) is in agreement with the CKM unitary prediction; thus, our conclusions in [1] do not change.
