  1. They represent the best fit of the system of differential equations (T4) to the experimental data (Fig. 5A,B). The global parameters (independent on the choice of the phtalocyanine) are highlighted in bold. The local parameters, i.e. the rate, kGen, of SO generation and the rate, kS,O, of SO quenching by S, are valid for all concentrations of the specific phtalocyanine.
