After securing doors on HAM2 (see LHO aLOG entry 12995), TFs have been taken over the weekend as part of Phase 3a testing to check for rubbing or other issues that may have developed as follows:-  

- MC1 M1-M1 undamped (2014-07-27_1090539018_H1SUSMC1_M1_damp_OFF_ALL_TFs.pdf)
- MC3 M1-M1 undamped (2014-07-26_1090401593_H1SUSMC3_M1_damp_OFF_ALL_TFs.pdf)
- PRM M1-M1 undamped (2014-07-26_1090403653_H1SUSPRM_M1_damp_OFF_ALL_TFs.pdf)

HAM2 ISI Status: ISI unlocked, ST1 damped, no isolation loops running.

MC1, MC3 & PRM alignment: No offset was applied during this measurement.

The undamped measurements from above have been compared with each other and the model (allhstss_2014-07-28_Phase3a_H1HSTSs_M1_Doff_ALL_ZOOMED_TFs.pdf).

Summary: 

MC1, MC3 & PRM show good agreement with the model and perform consistently, thus raising no concerns of rubbing.

Now need to check lower stage TFs and take power spectra.

All data, scripts and plots have been committed to the sus svn as of this entry.
