Comparison between APOGEE spectra of the star 2M01081597+5455148 (HD 6582, black) and two synthetic spectra (red straight line, with our pipeline’s best-fit parameters; blue dashed line with the CPS parameters for this star) for the APOGEE wavelength range. Shaded in gray are the areas used for χ² minimization by our pipeline’s algorithm. The best-fit parameters derived were T_eff = 5639 ± 163 K, log g = 4.46 ± 0.20 dex, [M/H] = −0.66 ± 0.07 dex, and the ones published in CPS were T_eff = 5316 ± 25 K, log g = 4.66 ± 0.028 dex, [M/H] = −0.73 ± 0.01 dex.
