Notes. Different databases from which we have taken the reflectance spectra of the MB asteroids shown in this table. See text for further details:
- BS: visible spectra (0.45-0.92 m), from databases SMASSI and SMASSII (Small Main Belt Asteroid Survey, Phase I and Phase II). References: Xu et al. (1995), Bus & Binzel 2002a,b.
- B16: near-infrared spectra (0.90-1.65 m) from the SMASSIR extension of the SMASS survey (Small Main Belt Asteroid Spectroscopic Survey in the near Infrared). Reference: Burbine et al. (2002).
- BIR: near-infrared spectra (0.8-2.5 m) from the MIT-UH-IRTF survey. Reference: MIT-UH-IRTF Joint Campaign for NEO Spectral Reconnaissance, http://smass.mit.edu/minus.html.
- DVNIR & DIR: visible and/or near-infrared spectra (0.5-2.5 m) of V-type asteroids ^(**) Reference: Duffard et al. (2004).
- dLVNIR: visible and/or near-infrared spectra (0.5-2.5 m) of some MB asteroids taken by the authors of this work.
- L3: visible spectra (0.49-0.92 m) from the S3OS2 survey (with a binning factor of 3). Reference: Lazzaro et al. (2004).
- 52C: near-infrared spectrophotometric data (0.8-2.5 m) from the 52-Color Asteroid Survey. Reference: Bell et al. (1995).
- MBOISS: near-infrared spectra (0.8-2.5 m) from the Main Belt Object near-Infrared Spectroscopic Survey, an observational ongoing sub-program of this survey.
