Comparison around the Nd II line between the RVS public spectrum of Gaia DR3 582056033834312320 (in black) and a model spectrum computed from its GSP-Spec parameters (in red). The cyan lines show synthetic spectra with Nd abundance ±0.2 dex around the adopted Nd abundance. The calibrated parameters of this star are S/N = 1110, T_eff = 3825 K, log(g) = 0.37, [Fe/H] = −0.74 dex, [α/Fe] = 0.12 dex, [Nd/Fe] = 0.12 dex, and [Ce/Fe] = 0.14 dex.
