Comparison between the observed spectrum of Ross 128 (2MASS J11474440+0048164), normalized using the template method (black), and a synthetic spectrum created using the literature (Souto et al. 2018) parameters for that star (red). The parameters used to generate the synthetic spectrum were T_eff = 3231 K, log g =4.96 dex, [M/H] = +0.03 dex. The ASPCAP preliminary parameters for this star are T_eff = 3212 K, log g =4.45 dex, [M/H] = −0.60 dex. The areas in gray represent the ones included in the line mask created from these spectra.
