Solar X-Ray spectroscopy from archived SMM Data: high resolution figures

Archived high-resolution X-ray spectra in the 13–22 Å range from the Flat Crystal Spectrometer (FCS) onboard SMM, are analyzed with reference to nonflaring active regions and to the Fe xvii line emission in light of laboratory and atomic data for nearby Fe xvi satellites. The satellites allow temperature to be found for these relatively low-temperature spectra, at which more conventional temperature-dependent line ratios are unavailable. By this means, the spectra can be arranged by temperature, showing that the Fe XVII lines are evident at temperatures of <3 MK.The repository contains high-resolution figures presenting the results of spectral analysis and text files with source data for Figures 5, 7, and 9.

针对搭载于太阳峰年卫星（Solar Maximum Mission, SMM）的平晶光谱仪（Flat Crystal Spectrometer, FCS）所获取的13–22埃（Å）范围内的存档高分辨率X射线光谱，本研究以非耀斑活动区为参照，并结合邻近铁十六离子（Fe XVI）伴线的实验室与原子数据，对铁十七离子（Fe XVII）的谱线发射特征展开分析。此类Fe XVI伴线可用于测定这类相对低温光谱的温度，而在该温度区间内，常规的温度依赖型谱线比值法无法使用。借此方法可将光谱按温度进行排序，结果显示Fe XVII谱线在低于3兆开尔文（MK）的温度下即可被观测到。本数据集仓库包含展示光谱分析结果的高分辨率图像文件，以及对应图5、图7和图9的原始数据文本文件。更多详细信息请参阅所关联的学术论文。
