GALFIT model and residuals. For each target, we show in the upper panel the contours of the HST data (black) and GALFIT model (green). The levels of the contours are at [3, 9, 27, 81] × RMS. The bottom panel shows the residual normalized to the noise map. The red cross shows the center of the main galaxy and the orange crosses show the center of additional components that were added to the fitting, when necessary.
