Aggressive isolation filters were designed on ISI-BSC6. UGFs are:
- 40Hz on all stage 1 DOFs
- 32Hz on all stage 2 DOFs.

The simulink diagram was completed to perform the sensor correction from stage 1 to stage 2. The model was recompiled and installed on h1seiey. Spectra were measured in the following configurations:
- Stage 1 super sensor with T240s blended at 250mHz on all DOFs.
- Stage 2 super sensor with blend at 250mHz on all DOFs.
- Sensor correction on both stages (except on Stage 1 Z)

Calibrated spectra of stage 2 are presented in attachment. Results are good.

The 2 high pass filters used for the sensor correction create a x10 amplification below 100mHz. It is less visible in the Z direction since the sensor correction is only engaged on stage 2.
