of many in/out signals for F0, F1, F2, BF in EXC type-A suspension because of temp increase by 0.4-0.5 C due to LED light ON in EXC1F room.
After these disturbances, some oscillation seems to exist and its damping rate seems to be very slow with a rate of a day. We should ask VIS group about this situation is healthy or not.
If the LED lights are tuned off again, the same thing will happen on the way of temp reduction.
