    • Zone notation is Γ (0,0), M (π,0), and Y (π,π) in units of 1/a, where a is the Cu-Cu distance.

    • Note that close to ω=0 the MDC peak width "levels off" due to the temperature term in Im Σ and the influence of experimental resolution.

    • In these EDC fits, the pseudogap was taken into account in the simplest possible manner by displacing the spectral peak to a larger binding energy.

    • We use the b term to estimate the bare velocity, as it is less subject to resolution and interpretation issues than the a term (see Ref. 28).

    • In the heavily overdoped case, where the renormalizations are weak and isotropic, we can make the approximation of using the true Fermi velocity rather than the bare one.

    • F0. In the limit of small Γ, the anisotropy of the MDC HWHM would follow that of Δ. This argument, though, would not explain the anisotropy of the EDC lineshapes at high binding energies observed in Fig. 1(a).
