Preliminary results from MCMC fitting of the sensing function measurements taken on Nov 12 to a 5 parameter model are given below:

  gain    : 1.160e+06     (nonlinear fit was 1.153e6, 0.6% different from MCMC)
  f_c     : 342.3340 Hz   (... 346.7 Hz, difference is 1.3%)
  delay   : -8.809e-08 s  (... -2e us, this value from nonlinar fit was ignored,
                               uncertainty on the value from the nonlinear fit was +/- 3.3 us)
  f_s     : 8.19 Hz       (... 7.389 Hz, difference is 9.8%)
  1/Q     : 0.0474        (... 0.0454, difference is 4.2%)

Values of the nonlinear fit were reported in LHO alog 31665.

The fitted sensing function and the corner plots are attached.

These are preliminary results, the uncertainties on the parameters have not been analyzed at the moment.
