Fig. 3
Examples of stars flagged as C, SB1, SB2 and LPV (see Sect. 3.2 for explanations). The spectra (plotted in different tones of gray) are corrected for heliocentric velocity, but not for telluric lines. The second component of the SB2 (marked with an arrow) is very dim and hence likely not detected at low-resolution.
