Table 3:

Some quantities characterizing the convective boundaries of the 3D model heflpopI.3d.
Pos.	$\Delta q$	h	N²	$u_{\rm e}$	$v_{\rm e}$	$v_{\exp}$
	[10⁸]	[10⁷ cm]	[ $\mbox{\ rad$^2 \mbox{\ s}^{-2}$ }$ ]	[ $\mbox{\ m~s${}^{-1}$ }$ ]	[ $\mbox{\ m~s${}^{-1}$ }$ ]	[ $\mbox{\ m~s${}^{-1}$ }$ ]
inner	9.7	1.0	0.92	1.0	<0.6	0.4
outer	6.5	1.2	0.14	3.9	6.7	0.7

Notes. Buoyancy jump $\Delta q$ (in $\mbox{$\mbox{\ erg}\mbox{\ g}^{-1}\mbox{\ s}^{-1}$ }$ ), square of the Brunt-Väisälä buoyancy frequency N², calculated interface migration velocity, $u_{\rm e}$ , and obtained from our simulation, $v_{\rm e}$ , and expansion velocity $v_{\exp}$ at the inner and outer convective interface of thickness h, respectively.
