Example images from the SDSS and DECaLS of galaxies of different classifications from our analysis; three examples of each classification are given, one per row. Split into three columns, each two panels wide, the left panel in a column shows an SDSS standard-depth color image of the galaxy, while the right panel shows the deeper DECaLS DR5 r-band image used in this work. The leftmost column shows galaxies classified as having no morphological disturbance, the middle column shows minor morphological disturbances, and the rightmost column shows major morphological disturbances. Note how for the minor, and even the major, disturbances the DECaLS images readily show LSB features that are barely noticeable or indeed totally absent in the SDSS imaging.
