Comment to In-vac health check of PRM (29936)

After offloading GAS filters, suspensions seem fine.
Figure 1-33 show the TFs of each DoF excitation.

Note that IMH1 and IMV2 OSEM efficiency becomes slightly smaller because they are close to the edge of the linear range but maybe acceptable.
Figure 34 and 35 show the OSEM inputs when performing in-air health check and in-vac health check, respectively
If you would like to recover the situation, I think we can use same procedure as PR2 (klog29918) and moving BF pitch to save IMH1 OSEM.
