    Contamination for 10:14:

    Empty ref cell: I=9.9 uA, Rate=490 hz, %of coda events passing the analysis cut=17%

    pol 3He cell: I=10uA, Rate=4.8 khz, % of coda events passing the analysis cut= 72%. This is steadily decreasing compared to previous kinematics (79% and 75%)

    -> we have less than 2% of events that are background, after analysis cut.

    With 39.35% and 76.1 % polarimetry and the assumption in the runplan that we loose 20% event from replay cuts, we are actualy taking 4% more events than expected.

    I don't modify the goal with these 4%
