a, b Out-of-plane Fermi surface (FS) maps in the ΓXM plane for the 2% Ce-doped sample—CCMO2 (a) and 4% Ce-doped—CCMO4 (b) measured with hv at the Mn 2p resonance. The white square designates the cubic pseudo-cell surface Brillouin zone (BZ). The doping clearly increases the experimental Luttinger volume. c Out-of-plane FS map for CCMO2 in the ΓZR plane recorded under variation of hv. d Sketch of the 643 eV line cutting the Γ8 point in the second BZ in k|| and the trajectory of the 643 eV energy in the k-space.
