HST cutouts, segmentation maps, and masks for the first 10 sources in order of RID. First column: 4″ × 4″ HST F775W cutout images. The purple dots and circles represent the positions of the UV-selected galaxy and r_in, respectively. Second column: 4″ × 4″ cutouts of the HST segmentation map. The yellow and green regions indicate the areas in which the target and neighboring galaxies are detected on the HST images, respectively. The segmentation map gives the boundaries of the objects. The dark purple regions indicate the sky. Third column: target’s continuum-component masks (in the spatial resolution of MUSE, 15″ × 15″). The yellow and dark purple regions present the mask (the area of the main part of the galaxy) and the sky, respectively. The violet circles show r_CoG. Fourth column: Neighboring object masks (neighbor mask; in the spatial resolution of MUSE, 15″ × 15″). The yellow and dark purple regions present the mask (the area of the main part of neighboring galaxies that have a bright continuum) and the sky, respectively.
