A capital Y indicates molecular outflow velocities exceeding the escape velocity for the nuclear region of the galaxy. References for the outflows/infall: NGC 4418 (González-Alfonso et al. 2012; Sakamoto et al. 2013; Costagliola et al. 2013; Veilleux et al. 2013); IC869 – this work; Zw049.057 Falstad et al. 2015); IRAS 17208-0014 Veilleux et al. (2013; but note recent work by Garcia-Burillo et al. (2015) where CO 2–1 outflow velocities of 800 km s-1 are found), Mrk231 (Fischer et al. 2010; Veilleux et al. 2013; González-Alfonso et al. 2014), IRAS 13120-5453 and IRAS 20551 (Veilleux et al. 2013), Arp220W (Sakamoto et al. 2009; Veilleux et al. 2013), SgrB2(m) (Rolffs et al. 2011b).

Minor axis dust lanes in the form of cones suggesting current or past outflows have been found in NGC 4418 (Sakamoto et al. 2013) and also in IC 860 (unpublished Nordic Optical Telescope U, B images by F. Costagliola). Also in Zw049.057 a peculiar minor axis outflow-like dust feature has been found Scoville et al. (2000).
