Check of the optimization gain after the modification to perform two pass to TT and one pass to HO1.Also an implementation of a quadratic fitting.

Test the system for bin 3 and 4, magnitude 15.7 to 17.3. The seeing turbulence was 0.8"


The start of the system went well.

Close loop set and the OCAM viewer wnet NOT LIVE with the loop close in the secondary and commands arrving to it.
Debugging Alfio and Fabio. Test different alternativies workaround but when the loop is close the OCAM was NOT LIVE and the secondary still receving bad frames.

It was observed that the WFSframes at the WFS showed to be corrupted and it was ONLY when the Adsec was power OFF it was availabel to recover the system to the normal operations.
There is a suspicious that bad frames "corrupted" between the Adsec adn the WFS triggered a fault in the WFS masterdiagnostic. This issue is under investigation by Arcetri and a possible solution of a better handshaking protocol could mitigate this issue.

Restore the system.

System ready for check the bin3 and bin4 optimization gain.

The magnitude from 15.7 to 16.3 were tested without problems.

The new implementation of bin3 and bin4 went well and it went through all steps (including the check flux ) to optical gain optimizations. The processes didn't show any execution problems. More details from Enrico emails.
Today-> preset timings. Next to use NONINTERVENTION MODE.

Let me know if the timings are corrects.
