During this shift we tested some DAS configurations to check the effect on the ITF.
More details on the different steps will follow tomorrow. The last test has been performed with P_in=125 mW and P_out=250 mW. This configuration seems close to the optimum working point.
We monitored the ITF behaviour with these DAS settings for about 3 hours. The ITF is stable, so we leave it locked with the DAS ON.
