Description
Vis-NIR reflectance spectra of a series of samples with a mix of 3 PAHs (Anthracene, Phenanthrene-d10 and Pyrene), JSC Mars-1 dust, PAHs mixed with CO2 snow with different abundances (0.1%, 0.54%, 0.67%) and 1.5% PAHs mixed with JSC Mars-1 dust
Number of spectra
21
Variable type(s)
  • sample composition
