Vienna Atomic Line Database

The Vienna Atomic Line Database (VALD) is a collection of atomic and molecular transition parameters of astronomical interest. VALD offers tools for selecting subsets of lines for typical astrophysical applications: line identification, preparing for spectroscopic observations, chemical composition and radial velocity measurements, model atmosphere calculations etc.

维也纳原子线数据库（VALD）汇聚了具有天文研究价值的原子和分子跃迁参数。该数据库提供了一系列工具，用以选取适用于典型天文应用的谱线子集：谱线识别、为光谱观测做准备、化学成分和径向速度的测量、模型大气计算等。
