Larger-scale context of the region surrounding NGC 4490 (left panel). Galaxies are color-coded by their velocity relative to that of NGC 4490, while those without velocity measurements are shown in yellow. The star symbol highlights the nearby, brighter spiral galaxy M 106. The dashed black line indicates the major axis of this larger-scale distribution of galaxies. It aligns with the orientation of the spatially flattened distribution of objects close to NGC 4490 of Fig. 1. The dashed square indicates the dimensions of that figure. The middle panel shows the distance of galaxies along this major axis, while the right panel shows the velocity of galaxies along this major axis. The dashed horizontal lines indicate the extent of the dashed square in the left panel.
