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).
