Single-track ATLAS-like Inner Detector hit data for Tracking Studies

A dataset to study the performance of tracking tools. The events contain single tracks with pile-up and detector noise according to Run 3 ATLAS conditions. More details can be found here. The root files contain two trees: "tree" and "track". The first contains the hit coordinates in mm and labels (1 - signal hit, 0 - pile up, -1 - noise). "Track" contains the truth z0 and pT of the track. The train, validation, and test files contain 398 996, 49 885, and 49878 events respectively.本数据集用于研究径迹重建工具的性能。其收录的事件均符合ATLAS实验Run 3运行条件，包含单径迹、堆集事件与探测器噪声场景。更多详情可参见此处。 该数据集的ROOT文件包含两棵TTree，分别命名为"tree"与"track"。其中"tree"存储以毫米为单位的探测器击中坐标以及标签（1代表信号击中、0代表堆集击中、-1代表噪声击中）；"track"则存储径迹的真实z0与横向动量pT（transverse momentum）。训练集、验证集与测试集文件分别包含398996、49885以及49878个事件。
