Configuration and Database for the Control System of the VISIR Instrument

J.F. Gournay, Y. Lussignol

A french-dutch consortium of institutes led by CEA/Saclay is designing and building VISIR [1] (VLT Imager and Spectrometer for the mid-InfraRed), a cryogenic multimode instrument for ground based astronomy at wavelengths of 10 and 20 5m. It will be mounted in 2002 at the focus of the fourth 8-meters telescope of the ESO VLT observatory in Chile. In order to control the different parts of the instrument, to interface the telescope and to perform observations, a suitable control system is being developed. It must adhere to common solutions which are used for all the VLT instruments. The VLT software [2] makes extensive use of configuration files, parameter files and data dictionaries to configure the instrument database, to perform observation and to store astronomical data. The overall layout of the control system will be described, the use of the VLT software will be discussed and a particular emphasis will be put on the benefit of the extensive use of a well defined and structured environment for configuration and data representation.
