1. Folder "TypeBp_PR_161115" includes simulated results about type-Bp suspension system, which was done in FY2016 by Y. Fujii.

-- Details of "TypeBp_PR_161115" -------------------------------------------------------------

2. The details of this calculation are summarized in the master's thesis by Y. Fujii (available from: https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=6060).

3. Folder "TypeBp_PR_161115" includes following directories and files:
 3-1. Folder "figures" includes the calculated plots for each filters, such as CLTF, OLTF and sensor-noise couplings etc.
 3-2. Folder "for_typeBp161115_**" basically includes plotting files.
 3-3. Folder "impulse_test" includes some plots of impulse response.
 3-4. Folder "MeasuredData" includes measured data of so-called type-Bp' system in the KAGRA mine on 2017.5.23. The test mass was freely suspended at that time.
 3-5. Folder "parameter" includes information of physical parameters of type-Bp suspension model.
 3-6. Folder "servofilter" includes the designed filters.
 3-7. Folder "sumconplot" includes plots of spectra and forced transfer functions predicted by SUMCON.
 3-8. Folder "eigenmodes" includes the pictures of the mechanical resonant mode shapes of the type-Bp suspension.

4. Feed back filters are designed in order to use in following 3 phases:
 > Damping phase (labeled "damp")
 > Lock-acquisition phase (labeled "lock")
 > Observation phase (labeled "obs").

5. Filter summary; damp5, damp6, lock8, obs8, and obs9 are considered in the thesis.
 > "damp5": 6 DoF for BF, 6 DoF for IM, 3 DoF for TM, 1 DoF for each GAS are controlled.
 > "damp6": 6 DoF for BF, 6 DoF for IM, *0 DoF* for TM, 1 DoF for each GAS are controlled.
 > "lock8": 6 DoF for BF, 4 DoF for IM, P&Y for IM-TM, L for TM, 1 DoF for each GAS are controlled.
 > "obs8": 5 DoF for BF, 3 DoF for IM, P&Y for IM-TM, 1 DoF for each GAS are controlled.
 > "obs9": 5 DoF for BF, *0 DoF* for IM, P&Y for IM-TM, 1 DoF for each GAS are controlled.
