We wonder if the flakiness of MC2 comes from the suspension or not.

To test it, we are shaking all of the suspension biases +/-1.0 with a script.

The script is here:

For this test, we closed the mechanical shutter before the MC.

Also some amount of misalignment is anticipated.
Don't be surprised if you see nothing is working when you come to the lab in the weekend.

I found the ITMY watchdogs tripped around 2:40 AM and then re-engaged it.
