Reflectance spectra of oldhamite and mixtures of oldhamite and enstatite of "Laboratory reflectance spectra of enstatite and oldhamite mixtures for comparison with Earth-based reflectance spectra of asteroid 2867 Šteins and Mercury"

This data is supplementary to Markus et al. (2024) Laboratory reflectance spectra of enstatite and oldhamite mixtures for comparison with Earth-based reflectance spectra of asteroid 2867 Šteins and Mercury. Planetary and Space Science 244, 105887. https://doi.org/10.1016/j.pss.2024.105887 The dataset comprises reflectance spectra of synthetic oldhamite and mixtures of this oldhamite with the orthoenstatite from Markus et al. (2018) from 0.3 to 17 µm as presented in Markus at al. (2024). First column gives wavelength in µm, second column gives reflectance. Incidence angle and emergence angles are both 15° with a resulting phase angle of 30°. Please note that in Markus et al. (2024) we only show the spectral regions from 0.3 to 1.0 µm and 4.5 to 16 µm. The spectral region between 1 and ~1.6 µm was difficult to measure for all samples containing oldhamite and we are therefore not confident about the quality of the spectra in this region. If you use these spectra, please also cite the PSS publication.本数据集为Markus等人（2024）的研究《用于对比小行星2867 Šteins与水星的地基反射光谱的顽火辉石（enstatite）和硫钙矿（Oldhamite）混合物实验室反射光谱》的补充数据，该研究发表于《行星与空间科学》（Planetary and Space Science）244卷，文章编号105887，DOI：https://doi.org/10.1016/j.pss.2024.105887。 本数据集包含合成硫钙矿（Oldhamite）以及该硫钙矿与Markus等人（2018）研究中的斜方顽火辉石（orthoenstatite）混合后的反射光谱，光谱波长覆盖范围为0.3至17 μm，相关细节详见Markus等人（2024）的论文。 数据集第一列为波长（单位：μm），第二列为反射率。实验设置入射角与出射角均为15°，对应的相位角为30°。 请注意，在Markus等人（2024）的原文中，仅展示了0.3至1.0 μm以及4.5至16 μm两个光谱区间。对于所有含硫钙矿的样品，1至约1.6 μm的光谱区间难以实现可靠测量，因此我们无法保证该区间内光谱数据的质量。 若使用本数据集的反射光谱，请一并引用该《行星与空间科学》（PSS）发表的论文。
