Re:ABELL 1809
This is a poor cluster, with no substructures. Oegerle & Hill (1994)
found no presence of substructures either. The VDP referred to the X-ray
center is very noisy in the center; thus, we prefer to show the VDP
referred to the galaxy density center, which shows a clear decrease
toward the central region.
