  We correct a numerical error which led to an overestimate of the baryon
asymmetry from supersymmetric electroweak baryogenesis in our paper
JHEP07(2000)018. Updated dependences of the baryon asymmetry on chargino mass
parameters and the bubble wall velocity are shown. We also include
LEP-II-constraints on the chargino mass parameters. Combined with our corrected
results for the baryon asymmetry these constraints imply that the phase in the
chargino mass matrix must violate CP nearly maximally in order to generate a
large enough baryon asymmetry. A number of other typographical errors are also
corrected.
