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）研究的补充数据，原研究题为《用于与小行星2867 斯泰因斯（2867 Šteins）及水星的地基反射光谱对比的顽火辉石（enstatite）与陨硫钙石（oldhamite）混合物实验室反射光谱》，发表于《行星与空间科学(Planetary and Space Science)》第244卷，文章编号105887，DOI：https://doi.org/10.1016/j.pss.2024.105887。 本数据集包含合成陨硫钙石（oldhamite）以及该陨硫钙石与斜方顽火辉石（orthoenstatite）混合物的反射光谱（reflectance spectra），光谱波长覆盖范围为0.3至17 μm，具体实验细节参见Markus等人（2024）的研究。 数据集第一列为以μm为单位的波长值，第二列为反射率数值。实验中入射角（incidence angle）与出射角（emergence angle）均为15°，对应的相角（phase angle）为30°。 需注意，Markus等人（2024）仅展示了0.3至1.0 μm以及4.5至16 μm两个光谱区间。对于所有含陨硫钙石的样品，1至约1.6 μm的光谱区间难以获得可靠测量结果，因此该区间的光谱质量无法得到保障。 若使用本数据集的光谱数据，请同时引用上述发表于《行星与空间科学(Planetary and Space Science)》的研究文章。
