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
