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).本数据集为配套《Ryugu颗粒中矿物与有机质的纳米尺度光谱识别与表征》一文的光谱与成像数据集。Spectra.dat 文件存储以波数为单位的原始光谱数据，其第一行标注各数据点的标题。Images.tar 中包含纳米傅里叶变换红外（nano-FTIR）相图，以及基于PsHet检测得到的A0030与C0034样品的形貌图、光学振幅图和光学相位图。相图的文件名采用“样品编号+对应波数”的格式（例如A1040代表样品A0030的1040 cm⁻¹成像结果）。
