Different examples of the interaction classification scheme. In the top panel, we show an unperturbed symmetric example (top left panel), CIG 100 (UGC 1863). The top middle and right panels show examples of perturbed galaxies. CIG 335 (NGC 2870) shows an overdensity in the halo region, and CIG 340 (IC 2487) shows a tidal stream in the southern region. All perturbation features are indicated with a black arrow. The bottom panels represent galaxies classified as cirrus-contaminated. CIG 1004 (NGC 7479), CIG 947 (NGC 7217), and CIG 154 (UGC 1706) are shown in the bottom left, middle, and right panels, respectively. These examples show considerable amounts of diffuse emission associated with Galactic cirrus only seen in our images. All of the images, except that of CIG 100, were smoothed with FABADA to enhance the structure.
