Optimisation results for photoreceptors undergoing multiple thermal reactions. a–c A red/far-red photoreceptor undergoing multiple thermal reversion reactions due to photoreceptor-chromophore interactions. a Comparison of optimal photoconversion cross-sections (‘Opt’) with those used as input (‘Input’). b Quantum yields obtained using algorithm (‘Opt’) compared with those used to create the synthetic data (‘Input’). c Comparison of synthetic data (circles) compared with simulations obtained using optimal parameters (lines) for our red-to-far-red (black) and far-red-to-red (red) experiments. d–f Same as in a–c for a red/far-red photoreceptor undergoing two thermal reversion rates due to dimerisation
