Examples of positive residuals for different values of ${\widehat{f}}_{\mathrm{scaled}}$, increasing from left to right. The top row shows the original images from the LOFAR dataset, the middle row shows the flux model, and the bottom row shows the positive residual flux. For the latter, the color values are scaled between 0 and 0.116, which is the maximum value of the depicted residuals. Values of ${\widehat{f}}_{\mathrm{scaled}}$ are indicated on top and values of Δ₊ on the bottom.
