 \caption{\label{galaxy_test}Numerical parameters of galaxy test runs. Tabulated are the model label~(1), and the input parameters: the number of particles (2), the softening parameter~$\varepsilon$ (3), and the time step $\Delta t$ (4). The units
 of length and time are $40~{\mbox {kpc}}$ and $250~{\mbox {Myr}}$, respectively.
 As a result of simulations the following control parameters are displayed:
 the relative change of components of the disc velocity dispersions~(5$-$7),
 the disc angular momentum loss (8), the Toomre's $Q$ parameter (9), the Toomre's $X$
 parameter (10), the average value of the distortion parameter (11), the conservation of
 the total energy (12) and the total angular momentum (13) of the system. Finally, we
 mention the code used (14).}
