Distribution of SEXTRACTOR stellarity index, CLASS_STAR of all objects found in the UKIDSS-GPS searched images. All objects with CLASS_STAR > 0.8 are stars, those with CLASS_STAR < 0.35, galaxies and 0.35 < CLASS_STAR < 0.8 are ambiguous objects. The open histogram shows the distribution of objected labelled as stars in the UKIDSS catalogue (MERGECLASS = −1) and the filled histogram are those labelled as galaxies (MERGECLASS = +1). The horizontal arrow points to a higher number count of ∼10⁵ in that bin that is not shown in the plot.
