Histogram showing the number of sources for each chemical species with abundances or equivalent widths in Gaia DR3 produced by the GSP-Spec Matisse-Gauguin method, in logarithmic scale. [α/Fe] is derived at the same time as the atmospheric parameters (T_eff, log g, [M/H]) and is available for approximately 5 million sources. A quality flag flags_gspspec is provided for the best use of the elemental abundances.
