Type: Summary 
Category: BHD 
Subject: Projected IFO noise budget, post-BHD upgrade 

Updated noise budget curves, now computed using the latest version of pygwinc. This resolves the inconsistency between the gwinc quantum noise curves and Gautam's analytic calculations. As before, the key configuration parameters are listed in the figure titles.

Attachment 1: Phase quadrature

Attachment 2: Amplitude quadrature

Attachment 3: Comparison to aLIGO design (phase quadrature)

Quote:

The quantum noise curves here are not correct. c.f. amplitude quadrature noise budget.
