Background fit results for the control and validation regions in the 1$\ell$4$b$ selection. The nominal predictions from MC simulation are given for comparison for the $t\bar{t}$ background, which is normalised to data. The "Others" category contains the contributions from $t\bar{t} WW$, $t\bar{t} t$, $t\bar{t} t\bar{t}$, $tZ$, and $tWZ$ production. Combined statistical and systematic uncertainties are given. The individual uncertainties can be correlated and do not necessarily add in quadrature to the total systematic uncertainty.
