Notes. The velocities are given in the z = 0.312710 restframe, as assumed by Kacprzak et al. (2010a). For Na i, we allowed fitlyman to vary the component’s centroid velocity within 2 km s-1 from the fixed values for the other ions. The values in brackets in column two are these slightly deviant velocities of the components in Na i. The upper limits for N(Na i) were derived from the signal-to-noise ratio without the need for specific component-velocities. The Doppler-parameters b are from the fits of the Ca ii lines. For the H i column densities, a proportionality between the column densities of Ca ii- & H i and an overall H i column density of log N(H i)= 21.71 are assumed.
