BEWARE: Work In Progress. Contributions are welcome.

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

Parameters for the limb darkening method.

Parameters:

• method (str, optional) – Method (among linear,quadratic,power2,nonlinear,uniform). Defaults to uniform (no limb darkening).

• coeffs (list, optional) – List of coefficients c1, c2, c3, c4 (depends on the method). Defaults to None.

factor_dict

get_func(method=None, coeffs=None)

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.

Parameters:

• dist_star (array) – Distance to star center normalized over the star radius (center = 0, edge = 1).

• method (str, optional) – Method to be used (see factor_dict). Defaults to None.

Returns:

Darkening coefficient (0 at star center).

Return type:

array
