Completeness for resolved sources as a function of flux density and ratio between the area of the source and the beam Q_A, for the fields J0249-0759 (left) and J1232-0224 (right). Completeness can be seen to linearly decrease in the log-log scale as a function of Q_A, showing that larger sources are harder to detect. Flux densities are compensated for the local noise in order to equalise completeness for different positions in the image. Pixels with no sources in them have been coloured grey.
