2023年7月2-8日，“巡天大数据分析研讨班第一期：恒星参数测定”在云南大学中国西南天文研究所召开。来自清华大学、北京师范大学、云南大学、中国科学院国家天文台、云南天文台、新疆天文台、南京天光所、南京大学、山东大学、三峡大学、西华师范大学、河北师范大学、贵州大学、新疆大学、中国科学技术大学、中国科学院大学、澳洲国立大学、法国斯特拉斯堡天文台、纽约大学等国内外高校和研究机构的100余位专家学者、博士后、研究生参加了研讨班。云南大学中国西南天文研究所所长刘晓为教授致欢迎词。

       研讨会期间，围绕大视场测光和光谱观测项目及定标、人工智能与光谱分析、恒星年龄测定，与会者分别介绍了各自领域的进展及面临的机遇与挑战。以此为基础，与会学者以“测光恒星物理参数”、“光谱恒星物理参数”、“双星和星团物理参数”、“恒星年龄和距离”、“星际消光和DIB”、“系外行星”、“时域天文和致密天体”、“选择效应”为主题，建立了多个研究小组，给小组成员密切协作，深入开展课题讨论和研究。研讨班的举办对巡天数据的深度挖掘和恒星参数测定方法的不断完善起到了积极的推动作用。

    On July 2-8, 2023, the first serial workshop "Astronomical Big Data Exploration Camp" on the theme Stellar Parameter Determination and Calibration was held at SWIFAR, Yunnan University. More than 100 scholars, postdocs and graduates from domestic and international universities and research institutions, including Tsinghua University, Beijing Normal University, Yunnan University, National Astronomical Observatory of China, Yunnan Observatory, Xinjiang Observatory, Nanjing Institute of Astronomical Optics & Technology, Nanjing University, Shandong University, China Three Gorges University, China West Normal University, Hebei Normal University, Guizhou University, Xinjiang University, University of Science and Technology of China, University of Chinese Academy of Sciences, Australian National University, Strasbourg Astronomical Observatory, and New York University participated in the workshop. Prof. Xiaowei Liu, Director of the South-Western Institute for Astronomical Research, delivered the welcome speech.

    During the workshop, experts specialized in the wide-field photometric and spectroscopic observations and calibrations, deep learning and spectroscopy, and stellar age determination presented the recent progress, and future opportunities and challenges of the related fields. Based on these, the participants engaged in in-depth discussions and research centered on topics ranging from "Photometric Stellar Physical Parameters", "Spectroscopic Stellar Physical Parameters", "Binary Stars and Star Clusters Physical Parameters", "Stellar Age and Distance", "Interstellar Extinction and Diffuse Interstellar Bands (DIB)", "Exoplanets", "Time-domain Astronomy and Compact Objects", to "Selection Effects". The workshop helped foster close collaborations, and played a positive role in promoting the deep exploration of survey data and the continuous improvement of stellar parameter determination methods.
