J2340−0053: For this system Na I D is lost in telluric absorptions. The C I structure is simple with two components. The Ca II doublet is detected although it is blended with weak sky features. We subtracted the latter. H2 is detected in this system. It is mentioned in Boissé et al. (2015), Balashev et al. (2015), who derived a column density of log N(H2) = 18.07 ± 0.06.
