Differences (this work - APOGEE spectroscopic estimates) in T_eff, log g, [Fe/H], ξ_micro, [C/Fe], [N/Fe], and [O/Fe] on the y-axis vs. the APOGEE spectroscopic estimates on the x-axis for the 44 stars in the solar neighborhood from our new IGRINS observations. T_eff, log g, and [Fe/H] are shown in the three panels in the top row, [C/Fe], [N/Fe], and [O/Fe] in the three panels in the middle row, and ξ_micro is plotted in the bottom row panel. The dashed black line indicates the difference value of 0.0 between APOGEE and our estimates. The mean difference and standard deviation (calculated as the middle value of the 84th–16th percentile values for each parameter) is indicated by the dashed red line and the red band, respectively, and is also listed in the respective panels.
