Spectral parameters used in this study reported on the Vesta spectrum. The spectrum is expressed in reflectance at incidence = 30° and emergence = 0° and is a median of the data acquired during the VH2 orbital phase. The two vertical black arrows on the inset indicate the position of the two ~506 and ~550 nm spin-forbidden bands. The dots represent the VIR visible spectral channels. The small feature at ~670 nm is the spectral counterpart of an order-sorting filter.
