An update of LHO's noise budget is attached ('NB07082015.png'). It used the data from 06/07/2015, at 4:00:00 am UTC, whose predicted BNS inspiral range should be ~60 Mpc according to the summary page. 

Some major updates are: 
1. in SUS/ETMY, updated the ESD driver gain and the TST filter.

2. in LSC Digital, replaced the OMC Front End block.

3. in addition to those already existed 'mystery' gain blocks, some new ones were added. In order to make the NB predicted data match the measured ones (at least at high frequencies) while maintaining each DOF's open loop transfer function consistent with the measurement ('LoopGain07082015.png'), those blocks had to be added before the injection of quantum vacuum noises to have the proper suppression. This seemed indicating that the optickle model was not working perfectly? 

4. A new front end calibration model was built to replace the old OAF.mdl. A comparison between the FE cal and NB was shown in 'FEcheck07082015.png'. In the plot all the blue curves were obtained from the FE Cal and green ones from the NB.

Besides, I also included two plots showing the coupling from MICH (SRCL) to DARM predicted by the NB model, which was generated by measuring TF from MICH (SRCL) control signal (in [ct]) to DARM sensor (in [ct]), then dividing it by the TF from DARM cal (in [m]) to DARM sensor, so the transfer function's unit was [m/ct]. See 'MICH2DARM07082015.png' and 'SRCL2DARM07082015.png'.
