NFW potential

class galpy.potential.NFWPotential(amp=1.0, a=1.0, normalize=False)

Class that implements the NFW potential

__init__(amp=1.0, a=1.0, normalize=False)

NAME:

__init__

PURPOSE:

Initialize a NFW potential

INPUT:

amp - amplitude to be applied to the potential

a - “scale” (in terms of Ro)

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.

OUTPUT:

(none)
