Magnitude, redshift, and field distribution for our sample of NB excess objects with observations available in two different NB118 filters (NBES). Those NBES objects with their magnitudes in the two contributing NB118 filters differing by more than 2.5σ are shown in color, with the colors referring to the different filter pairs. All other NBES objects are shown in the background in gray. Upper left: the difference in magnitude between the two individual contributing filters is plotted against the magnitude in the stack. Magnitudes were measured in 2′′ diameter apertures, and errorbars are 1σ uncertainties. Upper right: the J_corr − NB118 color excess is plotted against the magnitude difference between the individual NB118 filters. J_corr − NB118 is corrected for the continuum slope by means of the Y − J color (see Sect. 5.3.1). Lower left: J_corr − NB118 plotted against the photometric redshift (Ilbert et al. 2013). The three main groups are Hα (z ~ 0.8), [O iii]+ Hβ (z ~ 1.4), and [O ii] (z ~ 2.2). Different symbols refer to membership in these groups. The X (not in legend) labels objects with significant throughput variations, where no association with a specific line was possible. A histogram of the photometric redshifts is included in the upper part of this panel. The vertical lines indicate the redshift intervals that are used for the classification into [S iii] (dotted), Hα (solid), [O iii]+ Hβ (dashed), and [O ii] (dash-dotted). Lower right: position of the objects in the field of view. The DR2 NB118 stack is shown in the background. Larger symbols have a NB118 [ a ] − NB118 [ b ] > 0 and smaller symbols have NB118 [ a ] − NB118 [ b ] < 0.
