Dear all,

please find below a short summary of the activities of 17th on the mountain related to the AO system.

Italian people working at LBTO were:

L.Fini, M.Xompero

March 17th

Total # of person: 2

AO control SW

The management of data exipration for windspeed and elevation has been added to the Adsec Arbitrator. The algorithm for windspeed managemt has been improved adding some hysteresis.

The variable mirroring mechanism of AOS has been improved to support more variable types (float and short).

A new patch of AOS has been put into AO2 build and successfully tested.

A conflict with IIF sequence of operations has been discovered.

LBT672a

A new flat from W-CL operations has bneen computed.

The overcurrent protection setting procedure has been mdified in order to improve the behavior against the wind.
AOS tested for wind and elevation, with timeout expiration

Four external actuators were removed from control loop due to bad capsens readings and five actuators (four external and one internal) were removed from the control current integrator due to unstable capsens signals. The total number of actuators removed fromn the control loop is 26 and from the control current integrator 62.

A single shot fast link error was found on DSP#42,43 The high order mode offload procedure has been verified. It requires further tuning.

All the best

Luca
