distrib_uni_ball

erwans3.utils.distrib_uni_ball(npoint: int, r: Union[int, float, Quantity, ndarray] = 1, representation: Optional[Any] = None) → Any

Generate random points uniformly distributed within a ball.

Generate a list of npoint points that has a uniform distribution inside a ball of radius r. The output format can be selected with representation

Parameters:

  • npoint (int) – Number of points to generate.

  • r (int or float or Quantity or ndarray, optional) – Radius of the ball. Default is 1.

  • representation (Any, optional) – Representation type for the generated points (CartesianRepresentation, SkyCoord, np.ndarray, u.Quantity). If None, returns the points as a numpy array. Default is None.

Returns:

Random points in the specified representation type.

Return type:

Any
