Number counts in the H detection band, relatively to an area of ~16 sq. arcmin in order to be comparable with a region of the same area and with homogeneous depth from CANDELS GOODS-South DEEP (red shaded histogram). Blue line: IU counts; gray shadow: all detections, using SEXTRACTOR MAG_AUTO as total flux estimate; black solid line: IU (true) flux of the detected sources with an IU match.
