15 September 2004 The OmegaCAM instrument software: implementation and integration
Author Affiliations +
OmegaCAM is the wide field optical imager for the VLT Survey Telescope (VST), part of the VLT Observatory, operated by the European Southern Observatory (ESO). The camera consists of a mosaic of 32 4k x 2k CCDs, that almost completely fill with an array of 16k x 16k pixels its 1 degree squared field of view. The instrument will start scientific operations in the first quarter of 2005. In this paper, after a brief review of the instrument software design, we describe the functionality for each major software subsystem: ICS (Instrument Control Software) which is in charge of the control of the opto-mechanics, in particular of the filter system, AG, which takes care of autoguiding, IA (Image Analysis), in charge of measuring aberrations using a curvature-like wavefront sensor, OS (Observation Software) which coordinates all instrument subsystems in the execution of scientific observation and creates data files for the archive. Finally we report about the activities for the integration of the software with the opto-mechanics and the instrument electronics.
