Agreement between measured and expected radial trends at different sigma-clipping levels. Shown is the relative differences between the measured radial stacks from the simulated 12m+7m+tp cubes and the true stacks, as follows from the bottom left panel of Fig. 2, by subtracting the template trend. The difference between the different panels is that the data of the resulting stacks is clipped at 3, 5, or 10 S/N (Wσ_W). The stacking procedure is always the same. The hatched area denotes the regime, where the prior S/N/1 is detected in less than 20% of the pixels.
