a-f, energy-momentum spectra from the corresponding cuts 1–6 in main Fig. 1g. Red dots track the position of the peak associated with AF and green triangles track a higher energy hump feature (see main text). Grey dots in (e) track the only observable broad feature in this cut. Vertical black dashed line indicates the AF zone boundary. Grey line indicates the Fermi energy EF. Error bars correspond to the width of peaks in Energy distribution curve (EDC) fittings. g–l, EDCs of the momentum region indicated by the black double arrows in the respective cuts in a–f. Red, green, and grey dots indicate the same respective features as a-f. Black diamonds in l indicates the zone boundary dispersion and reconstructed electron pocket. The thick black line indicates the Fermi momentum kF, and the grey vertical line indicates EF.
