"Tab 12 Onshell WZ Signal Region Yields Table" of "Search for chargino--neutralino pair production in final states with three leptons and missing transverse momentum in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"

Observed and expected yields after the background-only fit in the SRs for the onshell $W!Z$ selection. The normalization factors of the $W!Z$ sample are extracted separately for the 0j, low-H_T and high-H_T regions, and are treated separately in the combined fit. The "Others" category contains the single-top, WW, triboson, Higgs and rare top processes. Combined statistical and systematic uncertainties are presented.
