"Pandora $1\gamma 1p$ NC Delta Radiative Decay Efficiencies" of "Enhanced Search for Neutral Current $\Delta$ Radiative Single-Photon Production in MicroBooNE"

2D efficiency matrix showing the efficiency of the Pandora $1\gamma 1p$ selection with respect to all true NC Delta Radiative Decay events which interact in the fiducial volume. The efficiency is shown as a function of true photon energy and angle. There are 10 bins from -1 to 1 in true photon $\cos \theta$ and 15 bins from 0 to 1500 MeV in true photon energy, with lower bin edges indicated in the table. NaN values indicate a "divide by zero" case where zero events were present in the bin before any selection was applied. This corresponds to Fig. 9 of the Supplemental Material.

本二维效率矩阵展示了Pandora单光子单质子（1γ1p）选择算法的效率，其统计基准为所有在 fiducial体积（fiducial volume）内发生相互作用的真实中性流（Neutral Current，NC）Δ辐射衰变事件。该效率以真实光子能量与真实光子角度为函数关系进行呈现。真实光子cosθ的分箱共设置10组，取值范围为-1至1；真实光子能量的分箱共设置15组，取值范围为0至1500 MeV，各分箱的下限值已在表格中列明。NaN（非数字）值代表"除以零"的异常情形，即未施加任何选择筛选时，该分箱内未统计到任何事件。该数据集对应补充材料中的图9。
