Abstract:

Sensitivity estimate for MICH, PRCL, SRCL, CARM, compared with DARM.

v1: Preliminary draft. Very rough suspension thermal noise.
v2: Added references for mirrors, updated Type-B suspension parameters.
v3-v5: Some more suspension parameters added, coating parameters updated.
v6: Added material properties for suspension wires.


To do: wire loss angles, suspension thermal noise calculations
