$^{a}$~The sign + ($-$) in the helicity column represents positive (negative) helicity.
$^{b}$~The unit of helicity is $10^{41}Mx^2$.
$^{c}$~The sign -- (+) in the rotation direction column represents the active region rotating clockwise (counter-clockwise).
$^{d}$~The unit of $\Delta $Ta is degree.
$^{e}$~T (F) shows that the active region satisfies (disobeys) Joy's law.
