"1$\gamma$0p Shower Angle Unconstrained Covariance Matrix" of "Inclusive Search for Anomalous Single-Photon Production in MicroBooNE"

Suppl. Fig. 9. The unconstrained covariance matrix for reconstructed shower angle for zero proton events. The matrix shows uncertainties and correlations between bins due to flux uncertainties, cross-section uncertainties, hadron reinteraction uncertainties, detector systematic uncertainties, Monte-Carlo statistical uncertainties, and dirt (outside cryostat) uncertainties. Data statistical uncertainties are not included. An example of how to add Pearson data statistical uncertainties can be found in the example code repository.

补充图9：零质子事件重建簇射角度的无约束协方差矩阵。该矩阵展示了由通量不确定性、截面不确定性、强子再相互作用不确定性、探测器系统不确定性、蒙特卡洛（Monte-Carlo）统计不确定性以及低温恒温器外部杂散源（dirt）不确定性所引发的各分箱间的不确定性与相关性。本矩阵未包含数据本身的统计不确定性。关于如何添加皮尔逊数据统计不确定性的示例，可在示例代码仓库中查阅。
