BeamSplitter Phase 2b Power Spectra

BS BSTS BSFM

Attached are plots of phase 2b power spectra for the beamsplitter installed in the test stand.
allbsfms_2013-02-25_H1_BS_Phase2b_ALL_Spectra_{Doff/Don}.pdf  file shows comparison between LLO BS (Phase 3a Oct 2012) and LHO BSTST(Phase 2b Feb 2013).
2013-02-25_1000_H1SUSBSTST_M{1/2}_ALL_Spectra.pdf show comparison between damping on and damping off.

**Resonnances from LHO are consistent with those from LLO.

**Damping is doing his job correctly

The plots all look good, nothing to notice in particular.

Transfer functions will be running overnight to finalize Phase 2b.

PS: The script *plotallbsfm_spectra.m* has been modified, after noticing a small mistake. The pdf files comparing data from different sites were created under the name allhstss_ instead of allbsfms_.
