Analysis of DARM time varying factors generated using the GDS calibration code

SudarshanK, RickS

Using the 16 Hz kappas generated by the GDS code from the C01 frames, we generated the differences between a given kappa value and the one immediately preceding it ("deltaKappas") with the caveat that we have pre-selected only the kappas for which the GDS state vector is greater or equal to 32735.
 
The first plot below is kappa_tst and kappa_C for the full period, about 9 days.
 
In the second through fifth plots below, the blue points are these deltaKappas and the red points are the deltaKappas that exceed the thresholds of +,- 0.0008 for deltaKappa_tst and +,- 0.002 for deltaKappa_C.
 
Plots:
The kappas for the whole 9 days.
The deltaKappas for the whole 9 days.
The deltaKappas for two one-day periods
The deltaKappas for one six-hour period
