ARPES spectrometers record the photoelectron intensity in an angular scale, independent of the spatial orientation of the surface normals. If this orientation does not coincide with the axis of the lens, the resulting contours of the Fermi surface will appear distorted. If the symmetry of the obtained pattern allows to identify the Γ-point, the map can be redrawn in momentum coordinates by standard formulas using rotation matrices. An example of such a recalculation is shown in Fig. S1.
