Two orthogonal views of the Arrowhead Supercluster edge-on to the plane of the structure as prescribed by the V-web analysis. The views are normal to the filament in the top panel and along the filament in the bottom panel (bounded by the gray surface in each panel). The yellow surface is the boundary of the Arrowhead defined by local flow patterns. Individual galaxies within the Arrowhead are identified by magenta points. Galaxies outside Arrowhead are in red if they participate in flows toward Laniakea, green if toward Perseus–Pisces, and blue if toward Coma. The location of the NGC 5353/54 Group and eight smaller groups are identified by the gridded spheres, scaled roughly to virial radii. The cardinal axes in the Arrowhead frame AX, AY, AZ are colored magenta, yellow, and cyan respectively. The lengths of the vectors are 1000 km s−1.
