Attenuation canon à 1 dB, nouvelle position du miroir M4 : PositionX = 410 mm, PositionY = 5380 mm

Calcul position BPM : barycentre X : 1.16e+06 +/- 1.88e+05 nm et Y = 8.06e+05 +/- 1.45e+05 nm, phase = 97 degres à 1 dB

A 0.5 dB, phase = 92 degres, barycentre X = 1.20e+06 +/- 2.17e+05 nm et Y = 6.3e+05 +/- 1.49e+05 nm

A 0 dB, phase = 76 degres, barycentre : X = 1.5e+06 +/- 2.95e+05 nm et Y = 3.52e+05 +/- 2.08e05 nm

On voit une évolution dans le barycentre mesuré sur les BPMs
