Examples illustrating our criteria for assigning or refusing to assign a close visual pair of galaxies as a merger. The top image is Galaxy 387, assigned as a merger because its secondary core is too close to the primary core to be registered as a separate galaxy, and it appears to lack its own undistorted halo. The center images are Galaxies 131 (left) and 1501 (right), two closely associated but otherwise distinct-looking early-type galaxies. The bottom images show Galaxies 1466 (left) and 1467 (right), also with well-separated cores and mostly independent envelopes. The blue streak emerging from the core of Galaxy 1467 may be a jet or lensed background galaxy. All images are 5 arcsec by 5 arcsec.
