AI总结：
该研究开发了开源模拟包corgisim，作为罗马日冕仪社区参与计划的一部分，用于南希·格蕾丝·罗马空间望远镜日冕仪观测的端到端模拟，为相关任务提供数据支持与应用指导。
AI中文摘要：
NASA的罗马空间望远镜将搭载一台探路者级日冕仪，以演示空间先进高对比度成像技术，为未来诸如宜居世界天文台等任务铺平道路。该日冕仪有望首次通过反射可见光获取木星类天体的成像、偏振测量及光谱数据。作为罗马日冕仪社区参与计划的一部分，我们开发了开源模拟包“corgisim”。该软件包基于成熟的光学传播库（包括PROPER和CGISim）构建，提供了一个用户友好、公开可用的Python框架，用于对日冕仪观测进行端到端模拟。该软件包可生成高保真、符合格式要求的数据，用于发射前校准、管道测试，以及目标选择、观测规划等社区应用。我们将概述corgisim的基础设施、功能及当前在计划中的成像、偏振测量和光谱模式下的实现情况，包括模拟主星、注入伴星及延伸盘的能力。我们还将重点介绍corgisim的适用应用场景，并为用户提供访问和使用该软件的指南。
英文摘要：
NASA's Roman Space Telescope will feature a pathfinder Coronagraph Instrument to demonstrate advanced high-contrast imaging from space, paving the way for future missions like the Habitable Worlds Observatory. The Coronagraph Instrument could obtain imaging, polarimetry and spectroscopy of Jupiter analogs in reflected visible light for the first time. We present the development of an open-source simulation package ``corgisim'' as part of the Roman Coronagraph Community Participate Program. Built on established optical propagation libraries including PROPER and CGISim, corgisim provides a user-friendly, publicly available Python framework for end-to-end simulations of the Coronagraph Instrument observations. The package produces high-fidelity, format-compliant data for pre-launch calibration, pipeline testing, and community applications such as target selection and observation planning. We will give an overview of corgisim's infrastructure, functionalities, and current implementation across planned imaging, polarimetry, and spectroscopy modes, including the ability to simulate host stars, injected companions, and extended disks. We will also highlight suitable applications of corgisim and provide guidance on how users can access and employ the software.
