Cluster candidate 11. The 1′ by 1′ false colour image of the cluster candidate is shown below the greyscale image. Image orientation is north up and east left. All the sources within a 4′ by 4′ box around the cluster candidate are plotted in the (H − K,J − H) colour−colour and (H − K,K) colour−magnitude plots. In the colour−colour plot blue dots are sources brighter than 17^m and green dots fainter than 17^m in K_s. The colour−colour and colour−magnitude diagrams, from left to right, are plotted using the AperMag3, AperMag1, and the AperMag4 magnitudes, respectively. The red crosses in the 1′ by 1′ greyscale image and the the red filled circles in the colour plots are sources (both stellar and non-stellar) in the cluster direction brighter than 17^m in K_s.
