Detection images in the four CLAUDS-HSC fields. The footprints of the different observations are over-plotted in different colors: The CLAUDS Deep layer u and u^⋆ bands in blue; the HSC-SSP grizy data in green; the VIDEO Near Infrared data in red (except in the XMM-LSS field where only two J band pointings are available, colored in pink). The footprints of the ultraDeep areas are shown with dashed lines.
