Near-IR Imaging of the Galaxy Cluster XMMU J2235.3-2557

Deep HAWK-I J and Ks imaging of the X-ray luminous galaxy cluster XMMU J2235.3-2557. The observations consisted of a mosaic of four pointings in two filters, with the centre of the cluster imaged in the four extreme corners of the HAWK-I detector mosaic. The fully processed images contiguously cover a 13’ by 13’ region at a pixel scale of 0.1065”. The image quality varies from 0.3” to 0.7” depending on filter and location. Data were taken under ESO programme ID 60.A-9284(H) as part of the first HAWK-I science verification run from 05-10-2007 to 15-10-2007.
