(amp=1.0, normalize=False)¶ Class that implements the Kepler potential
\[\Phi(r) = -\frac{\mathrm{amp}}{r}\]-
__init__
(amp=1.0, normalize=False)¶ NAME:
__init__PURPOSE:
initialize a Kepler potentialINPUT:
amp - amplitude to be applied to the potential (default: 1)
alpha - inner power
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.
