Each entry is a tuple (i_idx, j_idx, coefficients) where i_idx and j_idx are the indices of the involved channels and coefficients is the list of expansion coefficients for the energy dependence of the angle (a constant angle is a single element list). The energy dependence is expanded in the nui of the first channel of the model, see calc_frame_transformation_inner_closecoupling(). The default None means no mixing between the close-coupling channels.
