"Table 110" of "Measurement of distributions sensitive to the underlying event in inclusive Z-boson production in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector"

Away charged multiplicity distribution, Z-boson pT = 20 - 50 GeV, Dressed leptons : Statistical and systematic errors are added in quadrature.背向带电粒子多重数分布，Z玻色子横向动量（p_T）为20~50 GeV，穿衣轻子（dressed leptons）：统计误差与系统误差采用方和根法合成。
