   BEWARE: Work In Progress. Contributions are welcome.

   Module handling multiple limb darkening methods (linear,quadratic,power2,nonlinear,uniform).

   Parameters for the limb darkening method.

   :param method: Method (among linear,quadratic,power2,nonlinear,uniform). Defaults to uniform (no limb darkening).
   :type method: str, optional
   :param coeffs: List of coefficients c1, c2, c3, c4 (depends on the method). Defaults to None.
   :type coeffs: list, optional

   .. py:method:: get_func(method=None, coeffs=None)


   .. py:method:: compute(dist_star, method=None, coeffs=None)

      Function that parses which method should be used and return the corresponding darkening over an array of (normalized) distance to the center of the star.

      :param dist_star: Distance to star center normalized over the star radius (center = 0, edge = 1).
      :type dist_star: array
      :param method: Method to be used (see :attr:`factor_dict`). Defaults to None.
      :type method: str, optional

      :returns: Darkening coefficient (0 at star center).
      :rtype: array
