Notes. This table lists the sensitivity of the derived abundance ratios to changes in the input isochrones of Δt = −3 Gyr and −5 Gyr, Δ[Fe/H]i = +0.2 dex, and Δ [α/Fe] = +0.2, which are relative to a reference age of 13 Gyr, an input metallicity of [Fe/H]i = −2.0 and [α/Fe] = +0.2. The last column lists the changes when adopting a modified procedure for the continuum scaling (see Sect. 4.1.2 for details).
