Notes. OL and OPX stand for olivine and pyroxene, respectively; H+, He+, and Ar+ correspond to hydrogen, helium, and argon ions, respectively; p is the pressure in the vacuum chamber during the irradiation; i is the incidence, c the collection, and ϕ the phase angle of the spectral measurements; the subscripts stand for different wavelength ranges: V is the visible and N is the near-infrared. HEL indicates the University of Helsinki laboratories, PAR indicates the INGMAR set-up at IAS-CSNSM in Orsay, and PRG indicates the laboratories at Charles University in Prague.
