Data augmentation example for a CLM at redshift z = 0.531 (e.g. within the gravitational potential of M1149). Five HST bands are represented from the top to the bottom (F435, F606, F814, F105, F140). The first column shows the original cut-out, while the three rotations (90°, 180°, 270°) are reported in Cols. 2–4. The two vertical and horizontal flips are shown in the last two columns.
