(dens=<function AnySphericalPotential.<lambda>>, amp=1.0, normalize=False, ro=None, vo=None)[source]¶ NAME:
__init__PURPOSE:
Initialize the potential of an arbitrary spherical density distributionINPUT:
dens= (0.64/r/(1+r)**3) function of a single variable that gives the density as a function of radius (can return a Quantity)
amp= (1.) amplitude to be applied to the potential
- normalize - if True, normalize such that vc(1.,0.)=1., or, if
- given as a number, such that the force is this fraction of the force necessary to make vc(1.,0.)=1.
ro=, vo= distance and velocity scales for translation into internal units (default from configuration file)
