中国空间站望远镜CSST高精度数值模拟

中国空间站望远镜CSST高精度数值模拟是目前精度最高、耗机时最长、最为权威的针对CSST数值仿真的宇宙学数值模拟，其数据规模达到997TB，基本可以涵盖CSST整个生命周期里所能够拍摄的天区的数据情况，中国空间站望远镜CSST高精度数值模拟，是为中国第一个光学太空望远镜CSST（其意义相当于美国的哈勃太空望远镜，但视场、曝光深度、像质又大大优于哈勃，而且是可巡天）设计并运行的模拟，该模拟关乎CSST后续数据处理系统、软件开发、以及数据分析等重要项目。The high-precision numerical simulation of the China Space Station Telescope (CSST) is currently the most accurate, most computationally intensive, and most authoritative cosmological numerical simulation dedicated to CSST numerical emulation. With a total data size of 997 TB, it essentially covers the data scenarios of all sky fields that CSST will observe throughout its entire operational lifespan. This simulation is developed and executed for China's first optical space telescope CSST, which is equivalent in significance to the United States' Hubble Space Telescope but boasts a significantly larger field of view, deeper exposure depth, superior image quality, and is capable of conducting sky surveys. This simulation is critical for key projects including CSST's subsequent data processing systems, software development, and data analysis.
