Analyzing GDS calibration accuracy using recent broadband injection

[J. Kissel, A. Viets]

This analysis is similar to that done in LHO aLOG 51654.  I've used the broadband injection from Wednesday (2019-09-04): see LHO aLOG 51738.  The attached plot of DeltaL(f) / Pcal(f) during the injection includes 4 versions of calibration I made offline using the DCS pipeline:

  1. Real kappas: This version applies corrections for real parts of kappa_T, kappa_P, and kappa_U, as well as kappa_C and fcc
  2. Real kappas + SRC: This version applies corrections for real parts of kappa_T, kappa_P, and kappa_U, as well as kappa_C, fcc, f_s, and Q
  3. Complex kappas: This version applies corrections for complex values of kappa_T, kappa_P, and kappa_U, as well as kappa_C and fcc
  4. Complex kappas + SRC: This version applies corrections for complex values of kappa_T, kappa_P, and kappa_U, as well as kappa_C, fcc, f_s, and Q (everything)

Also included is the C00 data produced online using the GDS pipeline.  As expected, it agrees most closely with version 1 above.

This plot, as well as text files with the data, are available in the calibration SVN here:
