Description

Paper details measurements of the M-class asteroid and Rosetta flyby target 21 Lutetia from 2003-2008, investigating surficial variation in spectral properties. Data files show spectral comparison between different hydrated asteroids near 3 micrometers, using "type asteroids" for each main group that has been identified.
