Paper Abstract

The operation of a complex NIR imager/spectrograph with MOS has to accomplish different requirements with respect to the current development status of the instrument and of course to the type of user. For prototype- and lab-testing of the instrument direct control mechanisms of the different instrument units have to be available. They are normally used by experienced engineers. In the commissioning phase the user group expands towards people who want to use the instrument for their science programs. This user type needs easy and more indirect control mechanisms, because they don't want to move certain motors but change a filter for example. In case of LUCIFER, one of the first light instruments of the LBT, we have developed adequate software packages which try to satisfy the needs of observers and engineers. For example, we had to solve the problem of highly complicated MOS (Multi-Object-Spectroscopy) operations which have to be wrapped into safe software commands. For a normal mask exchange 63 safe MOS unit states had to be defined. The engineer is able to put the instrument into each of these states directly whereas the observer only needs three states to operate the instrument. In order to manage this we have used an appropriate software architecture which allows access to services at different levels. For the observers we present our operation preparation tool which allows a high flexibility during the process of observing block creation and an effective user interaction. Furthermore we give a report of our lab experiences with LUCIFER 1.
