Examples of the difference in the radial SB profiles for four different settings of the continuum subtractions. The black and blue lines indicate the SB profiles for the original minicubes and the continuum-subtracted minicubes, respectively. The neighboring masks were applied for both. The cyan shaded areas indicate the radii outside the target’s continuum-component masks and inside the r_CoG. Left column: RID = 4764, which has an artificial absorption trough with the general setting of a 200-pix (±100-pix) window. Right column: RID = 9863, which has a neighbor (at the radius shown by the magenta solid line) that cannot be eliminated only by the neighboring object mask. From top to bottom, each panel represents the settings: 1) 200-pix (±100-pix) window, 2) 200-pix (±100-pix) window + Lyα mask (±400 km s⁻¹ around Lyα), 3) 100-pix (±50-pix) window + Lyα mask, and 4) 60-pix (±30-pix) window + Lyα mask, respectively.
