5054−5257 Å (top) and 5608−5884 Å (bottom) regions of uncorrected disentangled spectra of the primary and the secondary components of GW Eri with selected spectral lines identified. Strong lines from ionised yttrium (Y IIλ 5087.42, 5200.41, 5205.72, and 5662.92 Å), and barium (Ba IIλ 5853.67 Å) are visible. The red lines denote the atmosphere model fits to the observed spectra (blue). The grey shaded areas were excluded from calculations by the use of an individual mask.
