Left panel: relation between Ca ii and H i column densities for seven Ca ii absorption systems. The solid line indicates the best fit through the data points, the dashed line indicates the relation found for Ca ii and H i in the Milky Way by Wakker & Mathis (2000). Right panel: relation between log (Ca ii/H i), scaled to the solar (Ca/H) ratio, and log N(H i) for the same absorbers. The solid line again indicates the best fit through the data points, while the dashed line shows the trend found in the Milky Way (Wakker & Mathis 2000).
