Integrated flux density to peak flux density ratio, as a function of the S/N of all images reduced with the LoTSS-DR2 pipelines. The left panel shows the catalogued sources of every LoTSS field concerned in this study, namely P297+30, P293+20, P289+10, P286+15, and P062+54 in black and the LoTSS reduced image of GalField3 in red. The right panel shows only the catalogued sources from the LoTSS image of GalField3. The black, dashed line marks the median ratio of integrated flux density to peak flux density for the source population, which is 2.013.
