... Design of Imaging Optics . Analyzing Optics . ... The high resolution near infrared camera (CONICA) for the first VLT unit telescope is under development. It serves as a multi-mode instrument for the wavelength region between 1.0 and 5.0 microns, providing diffraction-limited spatial resolution when combined with the adaptive optic system NAOS of the VLT (Rosset et al. ...

... The substepping technique is used for the Hubble Space Telescope (HST) imaging to cope with the problem of undersampling and to improve resolution. ... For the HST, undersampling means that the size of the pixel in a camera is larger than the critical value determined by the optics of the telescope, and aliasing takes place. ... Sampling is an operation to integrate a ( x ) within a pixel, and to assign the result to this pixel (Figure 1 A). ... Figure 1: Substepping ( N =2) and normal sampling. ...

... Overview and field layouts . ... Release Content . ... As part of the Great Observatories Origins Deep Survey ( GOODS ), near-infrared imaging observations of the Chandra Deep Field South (CDF-S) are being carried out in J, H, Ks bands, using the ISAAC instrument mounted at the Antu Unit Telescope of the VLT at ESO's Cerro Paranal Observatory, Chile. ... Since ISAAC observations are still ongoing, this release consists of J and Ks images of fields that have already been completed and are . ... 12600...
