Specifications for systems with O₂: total trajectory length T_run (ns), number of waters N_w, area/leaflet A (10⁻¹³ cm²), average number of O₂ in water N, concentration of O₂ in water ${\mathbf{c}}_{\mathbf{w}}\left({10}^{18}\hspace{0.17em}\text{c}{\text{m}}^{-3}\right)$, crossing rate r (10²⁰ cm⁻²s⁻¹), number of crossings with 95% confidence interval, and permeabilities (cm/s) from Transition-Based counting P (count) with 95% CI, and Bayesian Analysis P (BA)¹³; the standard error in the BA results is 3%.
