The magnitude of the photochemical parameters for HPPH.

Symbols	Initial valuesa	Calculated valuesb
$ϵ({\mathrm{cm}}^{-1}{\mu \mathrm{M}}^{-1})$	0.108	—
$\delta (\mu \mathrm{M})$	33	—
$\beta (\mu \mathrm{M})$	11.9 (Refs. 7,21,22)	—
$\sigma$ (${\mu \mathrm{M}}^{-1}$)	$(1\mathrm{to}10)\times {10}^{-5}$	$(1\pm 6)\times {10}^{-5}$
$\xi$ (${\mathrm{cm}}^2{\mathrm{mW}}^{-1}$${\mathrm{s}}^{-1}$)	$(10\mathrm{to}100)\times {10}^{-3}$	$(70\pm 40)\times {10}^{-3}$
$g(\mu \mathrm{M}{\mathrm{s}}^{-1})$	0.7 to 1.5	$1.5\pm 0.9$
${[{{}^1\mathrm{O}}_2]}_{\mathrm{rx},\mathrm{sh}}$ (mM)	0.5 to 1.0	$0.6\pm 0.1$

^aThe initial guess of the parameters, assigned randomly within the presented ranges.

^bThe obtained values by the macroscopic model with their overall error. Notice that the value of $\xi$ is significantly larger than that presented in Ref. 11. This is proportional to a change of $ϵ$ from 0.047, used in Ref. 11, to 0.108 based on experimental verification of the original literature value being based on ${\log }_{10}$ rather than ${\log }_{\mathrm{e}}$, as used in the current study. Each value is expressed as mean$\pm \text{standard deviation}$.
