... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...

These include the tasks used in the STScI pipeline, tools to generate the reference files used by the calibration pipeline tasks, and general image analysis, manipulation, and arithmetic tasks. ... Calnica is used to apply instrumental calibrations to individual datasets, while calnicb is used to process associated sets of NICMOS images. ...

... 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...
