Equivalent width of the Li i λ6708 Å line from Biazzo et al. (2017) vs. radial velocity measured in the present paper. The meaning of the symbols is as in Fig. 4. The average RV of the Lupus members (2.8 km s^-1) is indicated with the vertical dashed line, while the dotted lines delimit the 1σ confidence region. The blue and red histograms represent the RV distributions for the on-cloud and off-cloud Lupus stars found by Galli et al. (2013).
