Reproduction package for the paper "A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment"

This is a basic reproduction package for the paper "A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment" by Moroianu et al. (2025). It aims to provide the most important data products to check and reproduce the main results of the paper - namely, the burst and PRS localizations and the RM/DM analyses.本资源为Moroianu等人（2025）发表的论文《毫角秒（milliarcsecond）定位将快速射电暴（Fast Radio Burst, FRB）20190417A与紧致持久射电源（compact persistent radio source, PRS）及极端磁离子环境相关联》的基础复现套件。其旨在提供核心数据产物，以供验证与复现该论文的核心研究结果，具体包括暴源与PRS的定位分析，以及旋转量（Rotation Measure, RM）与色散量（Dispersion Measure, DM）分析。
