Let's try 400 modes

We still have the non-optimized pupils

Modal basis = KL_M585
type = Push-pull
Frames per mov = 3
Cycle = 1
#Modes = 400
Amp = 0.3
Note = IDL refuses the disturbance because of a too large force required!

Pupil optimization

TTMod = 0.5 mrad @ 100 Hz
Note: optimized with threshold = 2.39e-6. Not really round...

Try agin 400 modes

we flat the mirror in closed loop and re-acquire the pupils with the new flat

Starting over.
100 Hz, 200 modes

600 Hz, 400 modes

Pup = 113007
Dist = 105841
Iteration = 8

Rec.Close loop = 114212

REC 20110719 _114959
Modal Basis: KL_M585
intmatacq = 113828
n modes = 200
TT removal = OFF
cutted = 0
Note: high-order modes (>200) with low amplitude. Raw slopes dominated by static aberrations. But the mode shapes are nice and the SVD seems fine.

Works up to tt= 0.7, ho = 0.5
