Comparison of our best-fit models with the Euclidean normalized 1.4 GHz source counts for SFGs observed in the literature. The blue dash-dotted line, orange dashed line, and green dotted line show our best-fit source counts of Models A–C, respectively. The source counts from Hale et al. (2023) in the COSMOS and XMM-LSS fields are shown as purple right triangles and light blue pentagons, respectively. Also shown are the observed source counts from Smolčić et al. (2017a, green squares), Algera et al. (2020a, orange circles).
