Razor-thin exponential disk potential

class galpy.potential.RazorThinExponentialDiskPotential(amp=1.0, hr=0.3333333333333333, normalize=False, ro=None, vo=None, new=True, glorder=100)[source]

Class that implements the razor-thin exponential disk potential

\[\rho(R,z) = \mathrm{amp}\,\exp\left(-R/h_R\right)\,\delta(z)\]
__init__(amp=1.0, hr=0.3333333333333333, normalize=False, ro=None, vo=None, new=True, glorder=100)[source]

NAME:

__init__

PURPOSE:

initialize a razor-thin-exponential disk potential

INPUT:

amp - amplitude to be applied to the potential (default: 1); can be a Quantity with units of surface-mass or Gxsurface-mass

hr - disk scale-length (can be Quantity)

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)

OUTPUT:

RazorThinExponentialDiskPotential object
