Distribution of depth of the 1 μm band with respect to the spectral slope of every Gaia asteroid (grey dots). Red squares: raw slabs of the meteorite EC 002. Purple square: powder sample of the meteorite. Full orange diamond: barycentre of these four samples, and empty orange diamond: shifted barycentre along the ‘space weathering line’. The squares going from light blue to dark blue represent the modelled space-weathered spectra of EC 002, with different space weathering intensity. The orange ellipses are the 3-σ ellipse respectively around the barycentre and shifted following the space weathering behaviour of EC 002. The two dashed blue lines delimit a ‘possible matches area’, within which are represented asteroids matching EC 002. Pink dots: asteroids matching the raw slabs and powder sample of EC 002. Cyan dots: asteroids matching the space-weathered samples. Dark red dots: asteroids matching EC 002 by the curve matching method. Green dots: asteroids matching the space-weathered spectra of EC 002 by this same method.
