XAS data showing the charge transfer and orbital reconstruction effects of the interfacial CuO₂ layer. A) Schematics of the XAS experiment in FY and TEY modes. B and C) FY and TEY spectra and multipeak fits for the in-plane and out-of-plane components of the linearly polarized incident X-rays. Blue (red) shaded areas denote contributions with (${\mu }_{\mathrm{ab}}-{\mu }_{\mathrm{c}})>0$ (<0), where ${\mu }_{\mathrm{ab}}$ (${\mu }_{\mathrm{c}}$) is the net absorption along the in-plane (out-of-plane) direction, as explained in Section S1.1. (40).
