    2727|| '''16.09.2016''' || '''Michael Biermann (ARI)''' || '''GAIA as seen by a First Look Scientist[[BR]]'''[[BR]]As a daily routine, the Gaia First Look Scientists evaluate the quality of the scientific data and check the status of the Gaia instruments. In this talk a few examples out of the pool of findings by the Gaia First Look Scientists  will be presented and discussed. This should -on the one hand side- highlight the capability of this highly accurate astrometry mission, but -on the other hand side- also demonstrate the problems of the related data analysis work.

Since the topic is very  complex, important questions are still to be answered about the main  actors and their tasks. [[BR]][[BR]]The following topics will be discussed  in the second part: Who are the main actors? What means "responsibility"  with respect to occupational safety? What are the main tasks? What may  happen, if responsibilities are not assumed and tasks are not fulfilled? [[BR]][[BR]]Every  employee should know, which functions and activities are implemented at  MPIA. Not only every colleague should know who is responsible for  occupational safety, also the responsible persons should know about  their tasks, such that those become a practical reality in the  day-to-day work. And hence, the risk for accidents is automatically  reduced.
