我们提出了高分辨率的实验室测量的各种离子的C，N，O，F，Ne，S，Ar，Fe，和Ni的发射在极紫外波长带中心周围的λ211 Fe xiv通道的大气成像组件上的太阳动力学天文台。虽然该地区所有的强铁线都是众所周知的，但我们注意到许多尚未确定的弱铁线。我们测量的高分辨率也使我们能够解决Fe xi，Fe xii和Fe xiii中200到205 nm之间的几条线，这些线的身份是基于不同数据库之间的分歧而受到质疑的。除了铁之外，其他元素的光谱知之甚少，我们发现了大量数据库中还没有的谱线。例如，CHIANTI数据库与NIST数据列表中我们观察到的几条氩谱线明显不一致，而且它只包含了大约一半的硫谱线。
We present high-resolution laboratory measurements of the emission from various ions of C, N, O, F, Ne, S, Ar, Fe, and Ni in the extreme ultraviolet wavelength band centered around the λ211 Fe xiv channel of the Atmospheric Imaging Assembly on the Solar Dynamics Observatory. While all of the strong iron lines in this region are well known, we note many weaker lines of iron that are not yet identified. The high resolution of our measurements also allows us to resolve several lines in Fe xi, Fe xii, and Fe xiii between 200 and 205 Å, whose identities were in question based on a disagreement between different databases. The spectra of the elements other than iron are much less known, and we find a multitude of lines that are not yet in the databases. For example, the CHIANTI database clearly disagrees with the NIST data listings on several of the argon lines we observe and also it contains only about half of the observed sulfur lines.
