Notes. Table columns are as follows: Col. 1: HVC name as in Table 1; Col. 2: AGC identifier as in Table 1; Col. 3: applied taper: major axis (′′), minor axis (′′) and position angle (°); Col. 4: restoring beam: major axis (′′), minor axis (′′) and position angle (°); Col. 5: rms in a 4 km s-1 channel (mJy beam-1); Col. 6: column density rms in units of 1018 atoms cm-2 for an assumed linewidth of 20 km s-1.
