Summary of the relative variation of uncertainty sources (in %) considered for the evaluation of the systematic uncertainties in the different analyses. A filled or open circle signals whether that uncertainty affects the distribution or the absolute rate of a process in the fit, respectively. For some of the uncertainty sources “variable” is used to signal that the range is not unambiguously quantifiable by a range, as it depends on the value of the discriminants, event category and may also have a statistical component
