Top panel: ATCA CO(2 − 1) spectrum of LESS J0332 adopting a 90 km s^-1 binning (Coppin et al. 2010). Middle panel: APEX [C ii] 158 μm spectrum with a 28 km s^-1 binning (De Breuck et al. 2011). Bottom panel: ALMA [N ii] 205 μm spectrum with a 41 km s^-1 binning. All the spectrum is continuum-subtracted. The best-fit Gaussian profile is overlaid on the [C ii] and [N ii] spectra. The velocity is relative to the Lyα redshift, and the zero velocity is indicated by the dotted line.
