We did a quick measurement of the mode cleaner (IMC) modulation depth in this evening.

The modulatino depth was measured to be 0.1 radians.

To measure this, we locked the IMC on a sideband by simply flipping the control sign. This immediately gave us solid lock. The normalized transmitted power was measurement to be 0.003 with 10% error.

Probably an apparent logic for someones, but it would be nice to reduce a gap of the logic here: sqrt(0.003*4) =0.1 as (J1/J0)^2 seemed to be measured to 0.003.
