The distribution of the Subleading jet $p_{T}$ for events in the 2j2b region. The number of observed events (points) and estimated signal and background events (filled histograms) from the maximum likelihood fit are shown. The vertical bars on the points represent the statistical uncertainty in the data, and the hatched band the total uncertainty in the estimated events after the fit. The lower panels display the ratio of the data to the sum of the estimated events (points) after the fit, with the bands giving the corresponding uncertainties.

本数据集展示了2j2b事例区内各事例的次领头喷注横向动量（$p_T$）分布。图中呈现了观测到的事例数（数据点），以及通过最大似然拟合得到的信号与本底事例估算值（填充直方图）。数据点附带的垂直误差棒代表观测数据的统计不确定度，剖面线阴影带则代表拟合后估算事例的总不确定度。下方子图展示了数据与拟合后估算事例总和的比值（数据点），对应的误差带给出了该比值的相应不确定度。
