Atomic line fits for the M1.0 V star HD 233153 (J05415+534). The solid black and orange lines are the observed and synthetic spectra, respectively. The blue and pink shaded areas are the regions of comparison between the observed and the synthetic spectra (i.e. line masks) forfeatures in the VIS and NIR channels of CARMENES, respectively. The vertical dashed black lines mark the central wavelengths. The species, the central wavelength, and the effective Landé factor, g_eff, of the lines are indicated inside each box.
