^aDue to a heavy binning in the data, |$N_{\rm c}({\rm Mg\,\small {II}})$| and b_c are not well constrained in the Voigt profile analysis and serve only as a guide.

^bThe projected distances between different sightlines are |$(\overline{AB}, \overline{AC}, \overline{AD}, \overline{BC}, \overline{BD}, \overline{CD})=(8.8, 13.8, 10.3, 8.2, 12.2, 10.0)$| kpc.

^cAzimuthal angle of the QSO sightline from the major axis of the star-forming disc (measured counterclockwise).
