ST-ECF Technical Instrument Report WFC3-2009-04 The cross dispersion profiles of the WFC3 grisms H. Kuntschner, H. Bushouse, M. KЭmmel, J. R. Walsh April 30, 2009 ABS TRACT This document summarizes the analysis of the cross-dispersion profile width for the three grisms of the WFC3. For the IR grisms, the cross dispersion profile width derived from white light images and monochromator steps obtained in TV3 provide consistent results also in agreement with estimates derived from direct images. ...

... As modern observatories evolve to production units delivering data products and calibrated scientific data to the end users, new challenges arise in assessing the quality of data products. ... Taking the analogy of speed control on a motorway we can describe the system as a device (radar) collecting measurements of the system performance (passing cars). ... One of the direct applications of quality control is the verification of instrument performance based on the analysis of calibration exposures. ...

... 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...
