From left to right, relative difference between the size of the galaxy measured from the SAM truncation (denoted as R_0.5) and the semi-major axis of the truncation ellipse in BT24 (denoted as R_edge) as a function of: morphological type, redshift, apparent size (R_edge , semi-major axis of the BT24 truncation) split in quintiles, and axis ratio of the BT24 truncation. Boxes represent the IQR, while the horizontal lines indicate the median value. SAM truncations are on average overestimated with respect to BT24 truncations for the most elongated (in projection) and/or for the (apparently) smallest galaxies.
