galpy.potential.Potential.conc

Potential.conc(vo, ro, H=70.0, Om=0.3, overdens=200.0, wrtcrit=False)

NAME:

conc

PURPOSE:

return the concentration

INPUT:

vo - velocity unit in km/s

ro - length unit in kpc

H= (default: 70) Hubble constant in km/s/Mpc

Om= (default: 0.3) Omega matter

overdens= (200) overdensity which defines the virial radius

wrtcrit= (False) if True, the overdensity is wrt the critical density rather than the mean matter density

OUTPUT:

concentration (scale/rvir)
