Bus-DeMeo Asteroid Taxonomy Bundle 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.

由DeMeo等人于2009年提出的Bus-DeMeo小行星分类系统（Bus-DeMeo asteroid taxonomy classification system），基于在0.45至2.45微米波长范围内测得的371颗小行星的反射光谱特征构建。该系统共包含24个分类类别，采用主成分分析（principal component analysis）方法构建，其紧密遵循Bus于1999年提出的可见光波段分类系统，而该分类系统本身又依托Tholen 1984年提出的分类体系发展而来。Bus分类系统的绝大多数分类类别均得以保留，仅新增了一个Sv分类类别。本数据集收录了该系统所依托的371颗小行星的Bus-DeMeo系统分类表，同时还包含各分类类别的平均光谱数据。
