EDCs taken at six selected momenta (± k i , where i = 1, 2 or 3) with fixed spins and circular polarizations. In particular, the orange curves are obtained by measuring the EDCs at positive k values, right-circularly polarized light and spin-up channel ( C + ( k ,↑)), whereas the green curves are obtained with negative k values, left-circularly polarized light and spin-down channel ( C + (− k ,↓)).
