I have changed the DC biases on M1s of MC2 and MC3 yesterday for getting a good alignment of the IMC.

Since the IMC was needed to be locked for a short period I just tweaked the two suspensions as this is relatively easy and quick to get a good alignment.

Here are the suspension biases on M1 of MC2 and MC3 before and after my adjustment:
