Balanced Homodyne Detection

Displacement noise of OMC/LMC mirrors
Scatter loss in mirrors
Cavity design: triangle, quad ring, quad zig-zag (reference the new OMC paper from Koj)
Laser amplitude / frequency noise including DC offsets in various other lock points and motions to simulate bilinear noise
Oscillator noise: AM / FM
Aux length noise: MICH/PRC/ SRC
Req. on offsets/asymmetries: arm finesse, arm reflectivity, mass imbalance of ETMs
