Meyer, M.; Finger, G.; Mehrgan, H.; Stegmeier, J.; Moorwood, A. F. M.

Abstract:
The ESO Infrared Detector High Speed Arry Control and Processing Electronics, IRACE, is designed as a modular system which supports readout and data processing of arrays with four, and eventually more, output channels. The authors present here the principles of the system operation, the achieved readout and on-line processing speeds and present first measurement results with a 1024×1024 pixel IR array.

Abstract:
New details of the star-formation process have been revealed by a co-ordinated use of the ADONIS system on the 3.6-metre telescope at La Silla, in combination with data from the WFPC2 Camera of the Hubble Space Telescope. The authors illustrate some of the unique capabilities of the ADONIS system for high-resolution near-infrared observations of the stellar formation process.

Abstract:
A good knowledge of the point spread function (PSF) shape and of its possible variations within the field and with time is crucial when observations at the limit of the instrument capabilities are considered. In this note a quantitative estimate of the difference in instrument performances as a function of PSF changes, based on observations collected at the NTT, is reported.
