Data acquisition

The data acquisition with TurPol is slightly improved by using the auto-positioning-full for auto-guiding, also default for the other instruments. This actually makes a sufficient pointing correction that the target now always lands inside or very close to the diaphragms. The documentation has been updated accordingly.

The computer we had chosen as TurPol spare did not work properly (it refused to work correctly with the controller board). Instead, we found a suitable computer among the ones that were not being used at the KVA.

The main computer for TurPol failed the same day we were testing the spare (the CPU was blown due to poor cooling) and so we replaced it with the spare. Further testing of the original control computer (with new parts) has shown a more fundamental damage (or a faulty component replaced with another faulty one - to be determined). We are still lacking a functional replacement computer.
