Lensing region towards the J0033 (left panel) and J1527 (right panel) fields. The whitelight image is shown in greyscale. Only a portion of the full MUSE cubes are shown for clarity. The colored magenta rectangles denote regions of spaxels (Table 1) that contain background sources which have detected Mg II absorption. In both panels, the coordinates are relative to the center of the arc region in the respective field (Table 1). For J1527, the smaller cyan boxes denote the six apertures (A–F) from B22 whilst the red rectangle denotes the main region containing a nearby galaxy which contaminates a portion of the gravitational arc. The plate scale of the both images is 0.2″ per pixel.
