Abstract:

Calculation code and txt data for latest estimated sensitivity of bKAGRA.

kagra_sensitivity.pdf: Parameter list (.tex for source code)

kagra_sensitivity.m: MATLAB code for calculating the sensitivity

spectrum_(BRSE|BRSEhomo|DRSE).txt: Sensitivity data for BRSE, BRSE with homodyne, DRSE configurations. DRSE is the official final configuration.

VRSEcom.eps: Comparison plot of sensitivity curves for BRSE/DRSE

KSC_20170907b_sensitivity.pdf: Report from KSC Boards accepting this sensitivity curve, including report from referees (Kazuhiro Yamamoto, Takahiro Yamamoto, Yutaro Enomoto).

Notes and Changes:

v6; Approved by KSC, passed to EO (Sept 6, 2017)
v7: Report by K. Yamamoto was updated; added some more references to the parameter list and the code; updated miscellaneous coating parameters; checked again at the Chief Meeting on Oct 19, approved by EO on Oct 20, 2017.
v8: Corrected a bug at line 406 (related to input squeezing level). No effect on the latest estimated sensitivity.
v9: Updated spectrum_****.txt to update quantum_squeezing data.
