Fig. 5

Comparison of published Δ'¹⁷O (a–c) and recalculated Δ'¹⁷O using four different λ_RL and γ_RL (d–f). Gray symbol: λ_RL = 0.5305 and γ_RL = 0, light blue symbol: λ_RL = 0.528 and γ_RL = 0, orange symbol: λ_RL = 0.5278 and γ_RL = −0.040, light green: λ_RL = 0.5273 and γ_RL = −0.099 as mentioned in the text. The Δ'¹⁷O values change significantly according to the different set of λ_RL and γ_RL
