Centre of the GOODS-S field as observed with Hawk-I in the K-band (upper) and with WFC3/IR in the H-band (bottom). The displayed area is 1 arcmin wide, and is extracted from the region where the Hawk-I data have the maximum depth. The H-band image is from the CANDELS Deep area. Both images have a dynamic range extending from 0.5σ to 100σ per pixel, on a logarithmic scale. Objects encircled have H₁₆₀ ≃ 26 and a colour H − K ≃ 0.5, typical of faint galaxies.
