Continued from alog 73180.

IY mode 05/06 has been decreasing, although very slowly (after damping it for more than 12hrs with 50% of nominal gain value. i.e. -0.02).

Tony will ramp up the gain to nominal (-0.04) and watch over it for the next few hours. If it goes fine then the mode should be damped by tomorrow, else we will continue with reduced gain. I will check again in the morning.

I will switch ON damping gains for IY mode 04, 05, 07 and 08 tomorrow morning, once IY06 is under control.
