Nanoscale spectroscopic identification and characterization of minerals and organic matter in Ryugu particles

These are spectral and imaging datasets for the article titled "Nanoscale spectroscopic identification and characterization of minerals and organic matter in Ryugu particles". Spectra.dat contains raw spectra in wavenumbers. The first row contains title of each data point. Images.tar contains nano-FTIR phase images. Images.tar contains topography, optical amplitude, and optical phase maps of A0030 and C0034 based on PsHet detection. File names for the phase images indicate sample number followed by wavenumber (A1040 means sample A0030 and map of 1040 cm-1).本数据集为论文《Ryugu颗粒中矿物与有机质的纳米光谱识别与表征》配套的光谱与成像数据集。其中Spectra.dat文件存储了以波数为单位的原始光谱数据，其第一行为各数据点的标题。Images.tar文件包含纳米傅里叶变换红外（nano-FTIR）相图像，同时存储了基于PsHet检测得到的A0030与C0034样品的形貌图、光学振幅图及光学相位图。相图像的文件名命名规则为：样品编号后接波数（例如A1040代表A0030样品的1040 cm⁻¹图谱）。
