Same as in Fig. 1, but for the results of the CylSP method. In each panel, the red, and blue lines are the results of the CylSP method with R_min = 0.1, and 0.01, respectively, while the green lines correspond to the value calculated by the AGAMA software (see Sect. 3.2). The black line is the analytical result given by Merritt & Fridman (1996). Here N_z = N_R = 40, z_min = R_min, and R_max = z_max = 100, m_max = 12.
