In the original publication of the article, Figs. 3 and 5 are incorrect. The correct versions of Figs. 3 and 5 are given below:

figure a1

Fig. 3 Different types of 3D potentials represented from (29) over the parameter plane. Regions with bounded motions can be appreciated. All figures are “revolution plots” where \(x^{2}+y^{2}\equiv r^{2}\)

figure a2

Fig. 5 Effective potential and reduced radial flows. The value of the integral is \(G=0.1.\) Details of the region 4 are given in Fig. 7
