E. Holt at Palomar. Colin A. Peterson (b. 1977), a research support specialist at Cornell University, and responsible for designing sequences for the NEAR spacecraft Multi-Spectral Imager and Near-Infrared Spectrometer team, has developed innovative methods for obtaining spectral maps of (433) Eros. The name was suggested by J. Veverka.
