(amp=1.0, hr=0.3333333333333333, maxiter=20, tol=0.001, normalize=False, ro=None, vo=None, new=True, glorder=100)¶ NAME:
__init__PURPOSE:
initialize a razor-thin-exponential disk potentialINPUT:
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)
tol - relative accuracy of potential-evaluations
maxiter - scipy.integrate keyword
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)
