Dissecting pigment organization in APC trimers. (A) Multiparameter (brightness, FPol, and emission spectrum) mapping of all emissive levels observed in APC trimers. Dashed lines are guides to the eye for alignment. (B) Distribution of the spectral CM of levels showing a high degree of FPol. (C) Decomposed pigment-specific optical properties of the trimer. The two emission spectra were estimated by pooling the full spectra from each population in B separately. The absorption spectrum of β was approximated by one-half of that of the monomer. The absorption spectrum of α^R was estimated by subtracting the three β-pigments’ contribution from the absorption spectrum of the trimer (SI Appendix, Fig. S4).
