The results of the global CKM analysis include: Wolfenstein parameters, UT angles,
(combinations of) CKM elements, theory parameters and rare
branching fractions.
Detailed background information on the methodology and
the treatment of experimental and theoretical uncertainties
is provided in hep-ph/0406184.
Constraints from "Tree" quantities in the (ρ-bar,η-bar) plane
(γ(DK) and α from the isospin analysis with the help of sin2β (charmonium),
which gives another tree only γ measurement (the only assumption is that the
ΔI=3/2 b-->d EW penguin amplitude is negligible)).
Constraint on α/Φ2 from B→ρπ (U and I only).
The global constraint on α from B→ρπ is a combination
of the most recent BABAR and Belle data. This combination is not
just a naive average in α but a combination in the 26
experimentally measured U and I coefficients which are correlated
among each others. The correlation matrices are provided by both
experiments, BABAR and Belle. The combined constraint has a preferred
region around 120 degrees, and two suppressed regions around
30 and 85 degrees.

Constraints on γ/Φ3 from world average D(*)K decays
(GLW+ADS) and Dalitz analyses compared to the prediction from the global
CKM fit (not including these measurements). &gamma[combined]; = 77 +30 / – 32°
Constraints on |sin(2β+γ)| from the measurement of time-dependent CP asymmetries in
D(*) π (ρ). Summer 07 HFAG average is used as input. The extraction of the UT angles relies on SU(3)
symmetry for the estimates of the suppressed-to-leading amplitude ratios. We use for r(*) the values given in Max Baak's talk presented at CKM06 workshop

Translation of this result into γ (using sin(2β) as additional input and choosing
