^aWith a moderate spectral resolution, |$N_{\rm c}({\rm Mg\,\small {II}})$| and b_c are not well constrained in the Voigt profile analysis and serve only as a guide.

^bThe projected distances between different lensed sightlines at z = 0.7818 are |$(\overline{A^{\prime }C^{\prime }},\overline{A^{\prime }D^{\prime }}, \overline{C^{\prime }D^{\prime }})=(7.8, 5.7, 5.7)$| kpc.

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