Abstract

The performance of all scientific instruments of the Very Large Telescope (VLT) is monitored by the Quality Control (QC) Group of the European Southern Observatory. Basic goals are to detect instrumental failures on a short time basis and to evaluate and detect long-term trends. The QC process mainly involves pipeline-produced calibration products and is set up on a file by file basis. This implies that currently each detector or channel of an instrument is checked separately. All operational VLT instruments have a low number of detectors but with the advent of multi-detector instruments like OmegaCAM and VISTA, which have up to 32 individual detectors, this approach becomes unfeasible. In this paper, we present solutions for this problem for the VLT instrument VIMOS. With four detectors operating simultaneously, VIMOS can be regarded as a test bed for studying new QC concepts which can be implemented for other instruments with higher multiplicity.
