Optickle codes written by K.Somiya in order to derive the
requirement of the rms motion of each auxiliary DoF. Some
parts are copies from the Virgo Optickle codes. 

Single demodulation with 16.875MHz/45MHz PMs.

Run the codes in the following way.

1. Run path.m
2. Run run_matrix.m
3. Run run_matrix2.m

The rms motion of each mirror is defined in extractTF2.m.
The second run above is necessary to derive the optimal
feedforward function for the non-rms motion. The same
function is used in the third run but here the rms motion,
namely an offset on an mirror, is imposed.

IR2.dat is generated in the end that shows the inspiral
range for NS binaries. And results2.dat is the spectra of
total noise curves and loop noise curves including displacement
noise.
