$\dagger$ V = Visitor, S = Service. $\bullet$ Departure from linearity of the spectra. $\ddagger$ The two spectra of this object are very similar both in shape and slope. As the rotational period reported for this object is ambiguous, it is not possible to make a confident comparison between the rotational phases of each observation.
