The authors wish to make the following corrections to this paper [1]: we have found a typing error in the caption of Figure 9 (page 12)—T_s should have a value of 2220.3 K, not 220.3 K.

The correct caption of Figure 9 is

Figure 9. Non-linear curve fitting results for a spectrum from combustion of PyE sample, RMSE (root mean square error) = 0.4393, θ₀ = 0.0249, T_s = 2220.3 K, θ₁ (related to I₁ or Na) = 3.4583, θ₂ (related to I₂ or Na) = 15.7373, θ₃ (related to I₃ or FeO) = 6.2484, θ₄ (related to I₄ or Fe₃O₄) = 7.3093 and θ₅ (related to an offset) = 9.6 × 10^-8.

This change has no material impact on the conclusions of our paper. The authors would like to apologize for any inconvenience caused to the readers by this change.
