L_[C II/SFR ratio as a function of ΔMS for the three simulations (assuming they represent the same population), colour-coded by (Habing units). We binned the L_[C II/SFR ΔMS values to sizes of ∼0.1 dex. When we compare our results with Herrera-Camus et al. (2018a, their Fig. 6) (grey dots), it is clear that EAGLE simulations do not recover starburst galaxies with log ΔMS > 0.5, but there is a clear indication that deviations from the MS affects L_[C II/SFR.
