package is a tool for a global CKM
matrix analysis, offering the choice between many statistical approaches:
the Rfit (Range-fit) method, our frequentist approach described
in details in the note below.
the ERfit (Extended Range-fit) method (see the note below also).
the 95% CL Scan
method, the other frequentist approach from the BaBar Physics
a Bayesian approach.
Graphical results are displayed in several two and one dimensional representations
(such as the rho-eta plane), and numerical results are given for all the
relevant CKM parameterizations, CKM elements, Standard Model predictions
of rare K and B mesons decays, and theoretical parameters.
The CKMfitter package is writen in FORTRAN for older modules
and in C++ for recent developments. It is driven
by data-cards where running options and input parameters
