Flux density comparison for 1437 matched sources between TGSS and LOFAR MSSS HBA (gray dots). Due to the difference in resolution, the median MSSS to TGSS flux ratio (black dashed line) is biased upwards. When convolving the TGSS images to the MSSS resolution and repeating the matching (712 matches; red dots), the median MSSS to TGSSc flux ratio (red dashed line) reduces to close to unity. Flux densities for matched sources between TGSS and LOFAR HBA MSSS.
