Color (g, r, i) mages of the five UDGs that show signs of tidal disruption (from left to right: MATLAS-262, MATLAS-951, MATLAS-1059, MATLAS-1779 and MATLAS-1615). They show, from left to right: MATLAS-262 as a condensation within a long steam oriented in the east-west direction, close to perpendicular to an edge-on galaxy; the other filamentary structure close to the UDG with a NW-SE orientation is likely a foreground cirrus; MATLAS-951 has streams with a clear S-shape; MATLAS-1059 shows small tidal extensions; MATLAS-1779 has streams with a possible S-shape but there is contamination by a ghost stellar halo; and MATLAS-1615 displays streams oriented in the SE-NW direction but located in a high background region caused by multiple ghost stellar halos. From left to right, the image is 3, 25, 8, 25 and 25 sq.arcmin. in size. North is up and east is left.
