Time Varying Calibration Parameters- Updates

Calibration parameter updates that includes data until Nov 11.

Kappa_tst is slowly trending up after the bias sign flip on Oct 16  and rest of the paremeters show normal variations that we have seen in the past.

The first plot contains all the parameters that we calculate. 

The second plot highlights kappa_tst, kappa_C and cavity pole of which the kappa_tst and kappa_C will be applied to h(t).

This data is filtered for locked state using GDS state vector and thus contains some outliers at times when the IFO is locked but not in anlaysis ready state. In  future, we plan to use GDS state vector which will give us the flexibility to only use analysis ready data.

Correction: Data is filtered using guardian State vector not GDS.

Attached plot includes calibration parameters from Nov 12- Nov 30. This time the data has been filtered using GDS state vector and includes the data that has first four bit of GDS vector as 1. Detailed definition of the GDS state vector can be found here.

The output mat file from this calculation is located at the svn location below:

The plot showing the kappa trends are attached.
