    Column~1: simulation number and simulation type (c: cosmological simulations,
i: isolated simulations); 
 Col.~2: {\it Q} initial value of the disk;
 Col.~3: mass of the disk in $5.9\times 10^{10}~ M_{\odot}$;
 Col.~4: initial redshift  (for the cosmological cases);
Col.~5: initial DM mass inside the disk radius;
  Col.~6: initial halo-to-disk mass ratio inside the disk radius;
 Cols. 7 and 8: \citet{Efs82} parameters, where: $\alpha={r_0}^{-1}$, $v_{\rm m}$ is
the maximum rotational velocity, and $r_{\rm m}$ the corresponding radius; 
 Col.~9: type of halo used (for the isolated cases).
