J1302+2111: Both Na I and Ca II are detected for this system. The Na Iλ5891 line is clean, However, there is a spike close to Na Iλ5897 that prevents a direct measurement of the EW. We thus fit the doublet using VPFIT to derive the EW for Na Iλ5897. The Fe IIλ2586 and Fe IIλ2600 lines are strongly blended with sky absorptions, so we did not use them to fit the Fe II lines. C I is well fitted with one component.
