Left: Γ_D plotted as a function of ω_D, with the full parameter space on top and the boxed-in region zoomed in on the bottom. Right: Γ_G plotted as a function of ω_G, with the full parameter space on top and the boxed-in region zoomed in on the bottom. In the top images, the marker color indicates the petrologic type of the sample: type 1 (blue), type 2 (green), or type 3 (red). In the bottom images, the marker color indicates the specific meteorite. Markers without borders are the mean values of the maps, and their error bars represent the 1σ standard deviations. Markers with a black border are the values obtained for the single-spot spectra, and their error bars represent the 1σ confidence bounds.
