Larger field in XY coordinates at a distance of 31 Mpc. The X-axis follows the RA-axis, with positive numbers towards East, the Y-axis follows the Dec-axis, with positive numbers towards North. Colors indicate the line-of-sight velocities. The circles correspond to the NGC 474/NGC 470 system, the squares to the NGC 520 system, and the triangles to the NGC 488 system. The stars indicate field dwarfs (being outside of the virial radius). The virial radii of the systems are indicated with gray circles.
