PBL in the ASM IDL code: if the loadDisturbance command fails, to recall it you have to send first slopes w/o disturb and gain 0 to reset the ASM disturbance bit.

We have to close the loop on the off-axis sources to flatten the mirror because we are saturating the LGSW signals during calibration.

Pyramid K factor calibration

We load a 1.6" disturb and we close the loop on the FLAO. We inject a static aberration on the DM

Jitter compensation test

We insert the modulation at 10Hz in the tilt, 200nm PtV.

TN between 20141203_073742 and 20141203_074654 are all with jitter gain=0.0...

TN Notes
20141203_075523 Gj=0.5

we increase the frequency of the modulation to 50Hz. The AO loop is still closed on FLAO 150 modes.

Test of the LUCI window aberrations on PYR slopes_null

We inject LUCI window aberrations on the ASM as a static shape, we load a disturb equivalent to 0.8" (considering the no RR mode) and we close the loop on FLAO, 150 modes.

TN Notes
20141203_074631 no disturb
20141203_074739 0.8"

Test of the AIP QC

We center the on-axis source on the PYR: stages @ [-72.3; -47.3]mm

Now we center the on-axis source on the QC: stages @ [-73.25; -47.55]mm

The difference is about [0.95; 0.25]mm equivalent to about 1.6" on-sky. -- MarcoBonaglia - 18 Dec 2014
