pynbody.gravity.midplane_potential#
- pynbody.gravity.midplane_potential(f, rxy_points, eps=None)[source]#
Calculate the potential of a disk galaxy in the x-y midplane (with z=0)
- Parameters:
f – The snapshot to calculate the potential for
rxy_points – A list or array of radii at which to calculate the potential, in the xy-plane
eps – The gravitational softening length. See
pynbody.gravity.direct()for details of how this is used, or what happens when it is not specified.
- Returns:
v – The potential at the specified radii
- Return type:
