Lunar Spectroscopy
Data
This data set consists of
reflectance spectra of small lunar areas measured in 120
spectral channels from 0.62 to 2.6 micrometers using the
McCord circular-variable-filter (CVF) near-infrared
photometer. The data were acquired using the 2.2 m
telescope on Mauna Kea, Hawaii. The data were provided
by the Keck/NASA Reflectance Experiment Laboratory (RELAB)
at Brown University and archived by the PDS Geosciences
Node.
