Calculated structural and energetic parameters for Au-supported planar silicene with adsorbed Fe and Co at their different coverages N: the height of the adatom over the Au plane ($h_{MAu}$), the bond length between the adatom and its nearest Au atoms ($d_{MAu}$), the bond length between the adatom and its nearest Si atoms in the plane ($d_{MSi,h}$), the bond length between the adatom and the underneath Si atom ($d_{MSi,v}$), thickness of the silicene/Au structure defined as the difference between the largest and smallest z coordinates of Si and Au atoms ($\Delta z$), the binding energy of adatoms on silicene/Au ($E_b$), charge transferred from silicene to adatom ($\Delta {\rho }_M$), total magnetic moment of the system (${\mu }_{tot}$) in units of Bohr magneton (${\mu }_B$).
