Data for the paper, "MOCCA: Effects of pristine gas accretion and cluster migration on globular cluster evolution, global parameters and multiple stellar populations"

We provide the underlying data for results from MOCCA star cluster models that were reported in the paper, "MOCCA: Effects of pristine gas accretion and cluster migration on globular cluster evolution, global parameters and multiple stellar populations" (https://arxiv.org/abs/2411.06421). For each model presented in the paper, we provide the system.dat files from MOCCA which includes the evolution of more than 500 simulation parameters that are described in the header lines of the files (prefixed '#'). Within the compressed directory, the models are organized hierarchically by key physical parameters that characterize each star cluster simulation: The top-level directory indicates the concentration parameter (conc_pop_X), which specifies the ratio between the initial half-mass radius of the enriched and pristine stellar populations. The second-level directories follow the naming format Pristine_Enriched (e.g., 800000_300000) and indicate the initial number of pristine and enriched objects in the cluster model. Additional subdirectories specify other model parameters: Wo_X: the King model concentration parameter for the pristine population. Q_X: the initial virial ratio between the enriched and pristine populations. Rg, Rg_-1, Rg_-4, etc.: the galactocentric radius or its variation used in the model. Subfolders such as new_code, next, or devel_new_tdelay_fix indicate different code versions or development branches used for testing physical effects or numerical updates. old_tdelay_0: a specific model setup using the original time delay assumptions (see description in paper). Each terminal directory contains one or more system.dat files corresponding to a specific model configuration.本数据集提供论文《MOCCA：原始气体吸积与星团迁移对球状星团演化、整体参数及多重恒星族群的影响》（https://arxiv.org/abs/2411.06421）中报道的MOCCA星团模型结果的原始数据。针对论文中呈现的每一款模型，我们均提供MOCCA生成的system.dat文件，该文件包含超过500项模拟参数的演化历程，相关参数已在文件以#为前缀的头部行中予以说明。 在该压缩目录中，模型按照表征每颗星团模拟的关键物理参数进行层级化组织： 顶层目录对应集中度参数（conc_pop_X），该参数用于表征富恒星族群与原始恒星族群的初始半质量半径之比。 二级目录采用Pristine_Enriched命名格式（例如800000_300000），用于说明星团模型中原始与富恒星族群的初始天体数量。 其余子目录则用于指定其他模型参数： Wo_X：原始恒星族群的金斯模型（King model）集中度参数。 Q_X：富恒星族群与原始恒星族群的初始维里比。 Rg、Rg_-1、Rg_-4等：模型中使用的银心半径或其演化变量。 new_code、next、devel_new_tdelay_fix等子文件夹，代表用于测试物理效应或数值更新的不同代码版本与开发分支。 old_tdelay_0：采用原始时延假设的特定模型配置（详见论文中的说明）。 每个终端目录均包含一个或多个对应特定模型配置的system.dat文件。
