D0-D̄0 mixing and ratio of doubly Cabibbo-suppressed decays to Cabibbo-favored (CP) decays were studied. Systematic uncertainties were studied by evaluating the contributions from uncertainties in the probability density function (PDF) parametrization. The results show the limits on the mixing parameters by projecting the contours onto the corresponding coordinate axis on a graph. The improved limits on D 0-D̄0 mixing and CP violation in wrong-sign (WS) decays of D0 mesons were also set.
