BUS-DEMEO ASTEROID TAXONOMY V1.0

The Bus-DeMeo asteroid taxonomy classification system, described in DeMeo et al. (2009), is based on reflectance spectrum characteristics for 371 asteroids measured over the wavelength 0.45 to 2.45 microns. This system of 24 classes is constructed using principal component analysis, following most closely the visible wavelength taxonomy of Bus (1999), which itself builds upon the system of Tholen (1984). Nearly all of the Bus taxonomy classes are preserved, with one new class (Sv) defined. This data set includes a table of classifications in the Bus-DeMeo system for the 371 asteroids upon which the system is based. It also includes mean spectra for each of the classes.

DeMeo 等人于 2009 年所描述的 Bus-DeMeo 小行星分类系统，该系统基于对 371 颗小行星在波长 0.45 至 2.45 微米范围内的反射光谱特征进行测量。该系统由 24 个类别构成，采用主成分分析的方法构建，与 Bus 于 1999 年提出的可见光波长分类法紧密相连，而 Bus 的分类法本身又是建立在 Tholen 于 1984 年提出的体系之上。在 Bus 分类法的基础上，几乎保留了所有类别，并新增了一个类别（Sv）。本数据集包含基于该系统的 371 颗小行星的分类表，以及每个类别的平均光谱。
