Notes. Results from running simulations with all considered parameters combinations (for more details see Table 1). In the IMF parameters, s refers to standard, t-h to top-heavy, and b-h to bottom-heavy. For details on the 
and its relation with the free-fall time efficiency we refer the reader to Dutkowska & Kristensen (2022), where extensively discussed the impact of this factor. The four setups in the bottom of the table divided by the horizontal line refer to our high-z test (see Sect. 4.2). Since the test had impact only on the water emission, we did not provide the SFR – LFIR relations as these are the same as for the corresponding Galactic setups. The correlation between the LH2O – LFIR had consistent R2 ≈ 0.999, hence we do not provide the R2 values for this relation in the table.
