We took measurements on the C/DHARD yaw Loops with low bandwidth last Friday.

We firstly turned on the new filter to move compensation peaks for C/DHARD Yaw, then turn off the boost to win more phase. The gain was then lowered to ~half (CHARD_Y: -0.7 ---> -0.3, DHARD_Y: 40 ---> 19), and the new cutoff filters can be turned on.

These steps has been added in the Guardian, and we took measurements with the low noise loop, as attached below.

Both of the UGF are about 3.5Hz at 40 W now, which were ~5Hz before.
