Anisotropy of self-energy.
a, Peak positions determined by MDC and EDC are plot as dots overlaid with the TB band served as the bare band to extract self-energies. b, Extracted real part of self-energy Re ∑ along K-′′Γ′′ shown as open circles with error bars and the imaginary part of self-energy Im ∑ obtained by Kramers-Kronig relations from Re ∑ drawn as a continuous line. c. Im ∑ obtained by Kramers-Kronig relations and by measured widths responsible for the e-ph interactions show very good agreement.
