Measured NB excess as a function of the NB118 magnitude for all objects in the main NB118 detected catalog. Data is only included for the regions of overlapping filters and in each of the overlapping regions only for one of the two filters. The red-dotted horizontal line indicates the minimum required NB118 excess for objects that we classify as NB excess objects. In addition, the curves for a 4σ positive J_corr − NB118 [ i ] are shown for each of the 12 filters. The crosses show the median of the J_corr − NB118 in NB118 bins with a width of 0.5 mag. Finally, all mentioned lines are also plotted mirrored at J_corr − NB118 [ i ] = 0.
