J1122+1437: In this spectrum Ca II and Na I are both detected. The Ca II K line is clearly detected but not Ca II H (see Table 2). For the Na I D doublet, both lines are detected. However, Na Iλ5891 is strongly blended with a telluric feature but there is an apparent excess that can be estimated and subtracted (Fig. A.6b upper panel). Metal lines and C I absorptions are detected in one strong component plus several weaker components blueshifted by −170, −100, and −20 km s−1 relative to the main component.
