Lognormal parametrisation (Eq. (5)) between the halo mass (M_⊙) and ratio between the SFR and the baryonic accretion rate, η. We show two extreme cases: haloes near the efficiency peak contain subhaloes with very low mass (case 1), and very massive haloes that contain subhaloes near the efficiency peak (case 2). If the same recipe were used to calculate the satellite galaxy SFR in these two cases, unphysical values might result within the assumptions of our model, and therefore we suggest two different ways to calculate the SFR for satellite galaxies (Sect. 2.2).
