Subject: Projected IFO noise budget, post-BHD upgrade 

To supplement the material presented during the BHD review, I've put together a projected noise budget for the 40m. Note these are the expected interferometer noises (originating in the IFO itself), not BHD readout noises. The key parameters for each case are listed in the figure title. Also attached is a tarball (attachment 4) containing the ipython notebook, data files, and rolled-back version of pygwinc which were used to generate these figures.

Attachment 1: Phase quadrature readout.

Attachment 2: Comparison to aLIGO design sensitivity (phase quadrature).

Attachment 3: Amplitude quadrature readout.
