VSCL clusters and galaxies properties

We present six deep Near-InfraRed (JHKs) photometric catalogues of galaxies identified in six cluster candidates (VC02, VC04, VC05, VC08, VC10, and VC11) within the Vela Supercluster (VSCL) as part of our efforts to learn more about this large supercluster, which extends across the zone of avoidance (l = 272.{deg}5 +/- 20{deg}, b = +/-10{deg}, at cz ~ 18000 km/s). The observations were conducted with the InfraRed Survey Facility (IRSF), a 1.4-m telescope situated at the South African Astronomical Observatory (SAAO) in Sutherland.

The images in each cluster cover ~80 per cent of their respective Abell radii. We identified a total number of 1715 galaxies distributed over the six cluster candidates, of which only ~15 per cent were previously known. We study the structures and richnesses of the six clusters out to the cluster-centric completeness radius of r_c_ < 1.5 Mpc and magnitude completeness limit of K^o^_s_ < 15.5^m^, using their iso-density contour maps and radial density profiles.
