  We calculate the values and 1 sigma ranges of the running quark and lepton
Yukawa couplings as well as of the quark mixing parameters at various energy
scales, i.e. at M_Z, 1 TeV, 3 TeV, 10 TeV and at the GUT scale, to provide
useful input for model building. Above TeV energies, we assume the minimal
supersymmetric extension of the Standard Model, and include the
tan(beta)-enhanced one-loop supersymmetric threshold corrections which arise
when matching the SM to its SUSY extension. We calculate the GUT scale values
of the running parameters as well as their 1 sigma ranges, with the
supersymmetric threshold corrections included and with their effects
parametrised in a simple way.
