Absorption of photosystems and lamp spectra. Intensity spectra of the far-red (λ_max = 705 nm) and blue lamp (λ_max = 467 nm) used in the experiments to induce state 1 and state 2, respectively, PSI and PSII (C₂S₂M₂) absorbance spectra (normalized to their Q_y maximum), and PSI/(PSI + PSII) absorbance ratio spectrum.
