Fig. 4.
Large-scale environment around M 74 within ±500 km s−1. The width of the panel is 400′ (∼1 Mpc). Circles show the sizes of larger galaxies: 20′ for M 74, 10′ for NGC 660, 5′ for UGC 1176, and 1.4′ for UGC 1171 (a small circle next to UGC 1176). Crosses show the positions of additional galaxies detected at the HI line by ALFALFA (Haynes et al. 2018).
