TT-ONLY MATRIX

Trying to acquire a tt-only matrix on the sky to detect clocking.
Due to TSS enabled, adsec oversampling is 500Hz and that is the minimum frequency for the interaction matrix acquisition. This means low modulation (about 6 l/d).

121151 intmat disturb

nmodi=10
frames/cycle=5
cycles=40

Due to a bug in the disturbance routine the push-pull is not repeated 40 times, but only once!!

We try to repeat the acqusition many times to have some average. Guiding stopped in the middle, so a couple of auto-centers were done to recenter pupils between acquisitions.

Disturbo IM

Corretta la procedura che genera i disturbi, adesso abbiamo questi:

211014

modi=2 frames/modo=10
cycles=200
amp = optimized_amano_6l.fits

211629

modi=10 frames/modo=10
cycles=40
amp = optimized_amano_6l.fits
