  The precise measurements of the Bd oscillation frequency and the limit on the
Bs one one as well as the determination of the Cabibbo-Kobayashi-Maskawa matrix
element Vub improve the constraints on the other elements of this matrix.
  A fit to the experimental data and the theory calculations leads to the
determination of the vertex of the unitarity triangle as:
  rho = 0.160 -0.070 +0.094 eta = 0.381 -0.058 +0.061.
  The values of its angles, in their customary definition in terms of sines for
alpha and beta, are found to be:
  sin(2 alpha) = 0.06 -0.42 +0.35 sin(2 beta) = 0.75 +/- 0.09 gamma = 68
-12+11o.
  Indirect information on non-perturbative QCD parameters, on the presence of a
CP violating complex phase in the CKM matrix and on the Bs oscillation
frequency are also extracted.
