Commissioning campaign activity
rationale
The two main phases of the commissioning campaign follow the idea to
proceed in the test advancing in all system aspects (HW, control SW,data
reduction SW) at the same time. So, the first phase milestones is a closed
loop on-sky test with 200 modes and a bright star. This to recognize any
serious problem in any of the components or procedures used.
The second phase will then optimize the system in all aspects and will
contains the final test of the system on sky.
