Notes. The analytical value of the central density ρc and surface radius Rs are given in Cols. 4 and 5. The relative errors between the numerical and analytical estimations are provided in Cols. 7 and 8. The kinetic energy stored as numerical noise (normalized to the internal energy) and the level of energy conservation at the last calculated model are given in Cols. 9 and 10.
