Multi-component Voigt profile fits of S ii and Fe ii lines for the DLA systems at z_abs = 2.2930 in Q0216+080 (left panels) and at z_abs = 1.9200 in Q2206-199 (right panels). In each spectral region, we indicate the ion and rest-frame wavelength of the transition; the continuum and zero levels are indicated with solid and dashed lines, respectively. The radial velocity scale is obtained from the wavelength scale using the redshift of the strongest absorption component of each system as a reference. The velocity components used in the fits are marked with vertical ticks. The positions of the S ii velocity components (top panels) were constrained from the analysis of Fe ii lines outside the Ly α forest (bottom panels). The spectral region around the redshifted 2249 Å Fe ii lines in Q2206-199 (bottom right panel) is disturbed by a few cosmic events (emission spikes).
