Field of view within the EGS field. The positions of the detections are plotted with open circles: blue for already identified objects at lower redshifts (subsample 1) and gray for sources without an HST counterpart (subsample 2). Left panel: GTC/CIRCE deep image (NB1257 filter) with 18.3 h of exposure time. Middle panel: RMS noise contour map of the NB1257 image in ADU/s. Right panel: HST/WFC3 image (F125W filter) with 25.9 h of exposure time. Orientation: North is up, and east is to the left. Size: 2.6 × 2.6 arcmin².
