Vienna Atomic Line Database
收藏资源简介:
Vienna Atomic Line Database (VALD) 是一个收集天文学相关原子和分子跃迁参数的数据库。该数据库提供工具用于选择典型天体物理应用的谱线子集,包括谱线识别、光谱观测准备、化学成分和径向速度测量、大气模型计算等。VALD 定期更新经过严格评估的数据集,由专家团队研究数据的统计特性,比较不同数据源的结果,并为每个新数据源建立质量评级。
Vienna Atomic Line Database (VALD) is a database that collects atomic and molecular transition parameters related to astronomy. This database provides tools for selecting subsets of spectral lines for typical astrophysical applications, including spectral line identification, preparation of spectroscopic observations, measurement of chemical compositions and radial velocities, and atmospheric model computation. VALD regularly updates its rigorously evaluated datasets. Its expert team studies the statistical properties of the data, compares results from different data sources, and establishes quality ratings for each new data source.
