Illustration of how the gas infall and the gas masses (of ISM and corona) are governed by the model parameter “star formation efficiency”, θ₄ = SFE. The upper panel shows the infall over time for and ± 2σ_prior deviations. For comparison, a model with but a Schmidt law exponent of 1.4 instead of our default 1.0 is shown (then the SFE parameter is no longer equal to the star formation efficiency). In the lower panel, gas mass of the corona (solid lines) and the ISM (dashed lines) are depicted for the four different cases from above, normalized to . The SFR and its cumulative version are plotted in the upper and lower panel, respectively.
