I changed the channel to plot from IMC-MCL_SERVO_OUT_DQ to IMC-SERVO_SLOW_DAQ_OUT_DQ.

Tanaka-san noticed that IMC-MCL_SERVO_OUT_DQ has integral filter and better to use another channel.
Therefore I decided to use IMC-SERVO_SLOW_DAQ_OUT_DQ channel.
I also changed the seismometer plot to a 3-10 Hz BLRMS plot which seems to have a greater relationship to IMC.
