Table 4: Abundance changes for each ion in HR 5049. $\Delta M$: the abundance difference due to the change of the metallicity from [M/H] = 1.0 to 0.0. $\Delta T$+: $T_{\rm eff}=10~300$ K + 300 K (increase $T_{\rm eff}$ by 300 K), $\Delta T$-: $T_{\rm eff}=10~300$ K - 300 K, $\Delta G$+: log  g = 3.81 + 0.2, and $\Delta G-$: log  g = 3.81 - 0.2.
