A link-type seismic tie is provided between a steel structural support and a buckstay, and includes two horizontally arranged, parallel, and spaced apart link members, which are connected at their ends to large vertical pins. In a compact photovoltaic cell arrangement, each cell is shielded from direct radiation by the adjacent reflector. A pupil mirror manipulator operatively connected to the pupil mirror and configured to vary the shape of the reflective surface of the pupil mirror allows for dynamically correcting imaging aberrations originating from lens heating, compaction and other radiation induced imaging aberrations occurring during operation of the projection objective. For each scanned entry, detection is made whether the respective frequency channel actually contains the carrier of the respective RAT. The data collection unit performs a data collection process of reading the device data from the device memory via the internal bus, and storing the read device data in the built-in database. At least part of the optics are designed andor arranged such that at least part of the light beams is deflected and guided through the receptacles at an angle to the radially outward direction on the disk-like body which means at an angle to the radius, connecting the respective optics with the rotation axis of the disk-like body.
