We flatten with FLAO and ARGOS
We load disturb =
1.2" and we set diodes to have about 4k ADU per subap.

Now the LGS are centered on the LGSW
FoV, we take the new hexapod positions
We noe close the loop on FLAO, bin1, 400 modes.

Measure of LGSW FoV center with FLAO stages
We close the loop on FLAO, we move the stages to feed off-axis sources on the LGSW. Now we scan the 3 LGS
FoVs and we write down the stages positions at which the LGS exit the

Now we set the stages to the best center position of the 3 LGS, we close the jitter loop and we take the new
