Examples of dwarf interaction features. (a) Low surface brightness pair with MATLAS-1783 (north of center) and MATLAS-1784 (south of center) and a central bridge extending in the center of the image from MATLAS-1783 to MATLAS-1784; (b) The antennae-like system MATLAS-546; (c) MATLAS-602, showing faint shell features on both sides; (d) MATLAS-824, also showing faint shell features on both sides. The images are 1.75′ × 1.75′ for (a) and (c), and 1.5′ × 1.5′ for (b) and (d), with north up and east left. RGB images were produced with the help of the ASTROPY package, based on the method from Lupton et al. (2004).
