1400 MHz Euclidean normalized differential source counts. Top: The source counts of our GPS sample. Plotted are also the source counts of the PS sample from Snellen et al. (1998). To compare our source counts to those of a general population of AGN, the 1400 MHz source counts from De Zotti et al. (2009) are plotted. The 1400 MHz source counts from the T-RECS simulation (Bonaldi et al. 2019) are indicated. The 1400 MHz model of large-scale AGN from Massardi et al. (2010) is indicated by the solid gray line. This same model scaled down by a factor of 28 is indicated by the dashed gray line. Bottom: residuals of our GPS source counts to the Massardi et al. (2010) 1400 MHz model rescaled by a factor 28.
