报告题目：CFHT and DECam Image Processing based on the LSST Science Pipelines

　　报告人：刘滨阳 博士（CGG，USA）

　　报告摘要：As one of the Stage IV dark energy surveys, Rubin Observatory LSST has started commissioning recently, and will conduct its 10-year survey for the southern sky area of over 20,000 square degree. Its state-of-the-art image processing pipeline, the LSST Science Pipelines, is designed to serve as one of the highest quality general-purpose general-dataset pipelines in astronomy. The LSST Science Pipelines will coordinate goals from different scientific cases, and produce a graceful catalog for studies in both static sky and time domain astronomy. In this talk, I will briefly introduce the infrastructure and data flow in the LSST Science Pipelines, as well as its applications in processing datasets from existing telescopes, such as DECam and CFHT. Meanwhile, I will give a quick update on the working progress of our current project of CFHT image processing and analysis.

　　作为第四代暗能量巡天项目之一，LSST已于今年开始试运行，并将开展为期十年的巡天计划，其巡天计划将覆盖超过20000平方度的全部南天球。同时，作为LSST的图像处理和分析系统，LSST科学管线软件(LSST Science Pipelines)以最高质量的通用天文管线作为设计目标，协同不同科学目标并适配不同科学仪器的数据产出，致力于生成同时适用于静态天空和时域天文学的巡天目录。在此次报告中，我将简要说明LSST科学管线的基本构架和工作流程，并以DECam和CFHT为例，介绍其在处理现存望远镜的观测数据中的应用，同时，对目前的CFHT图像处理和数据分析工作进展进行报告。
