Data used in "CO2 infrared spectra on silicate dust grain analogs: Implications for JWST observations"

This dataset contains reflection-absorption infrared (RAIR) spectra of CO₂ deposited on both bare and ice-coated amorphous silicate (MgFeSiO₄) films on gold (Au). The type of ice layer used is indicated in the file name. Each set includes multiple spectra collected at different temperature intervals, also noted in the file names. Each individual file is a text file with wavenumbers (cm⁻¹) on the X-axis and optical depth on the Y-axis. The data is published in the Astrophysical journal letters (10.3847/2041-8213/ade993).本数据集包含沉积于金（Au）基底上的裸态与冰包覆非晶硅酸盐（MgFeSiO₄）薄膜表面的二氧化碳（CO₂）反射吸收红外（reflection-absorption infrared, RAIR）光谱。所用冰层的类型已在文件名中标注。每组数据集包含多组在不同温度区间采集的光谱，相关温度信息同样标注于文件名中。每个独立文件均为文本格式，其横坐标为波数（cm⁻¹），纵坐标为光学深度。 本数据集已发表于《天体物理学杂志快报》（Astrophysical Journal Letters），DOI编号为10.3847/2041-8213/ade993。
