Examples of candidates classified as non-LSBG during visual inspection because of lack of sufficient signal in the g-band (a) are shown in the top panel. Candidates classified as non-LSBG during visual inspection because of being artefacts are shown in the lower panel (b). The RGB images are created using the g, r, and z bands with the APLpy package (Robitaille & Bressert 2012). Each image corresponds to a 67.32″ × 67.32″ region of the sky with the candidate at its centre.
