Overview of the MAGNET field. Small points show existing spectroscopically confirmed galaxies at z < 0.04. Larger circles show the location of the groups falling in the MAGNET footprint, shown in black. The size of the circles is proportional to the group virial radii. Both circles and points are color coded by redshift. Cyan (purple) solid lines indicate the filament network identified by DisPerSE using galaxies in the range 0 < z < 0.02 (0.02 < z < 0.04). The only structures shown outside the MAGNET footprint are three clusters that are located more than 10° away from our field: Centaurus, Hydra, and Antlia.
