Main properties of the cluster Abell 209.
| BCG (α,δ)J2000 |
|
| Mean redshift | 0.2090 ± 0.0004 |
| Velocity dispersion [km s-1] |
|
| Virial radius r200 [Mpc] | 2.13 ± 0.05 |
Notes. The radius r200 corresponds to the radius of a sphere whose mass overdensity is 200 times the critical density at the cluster redshift. The value of the redshift is taken from Mercurio et al. (2003a). The velocity dispersion is calculated on our dataset (Sartoris et al., in prep.), while the virial radius is taken from Merten et al. (2015).
