C. Cahillane Today I have fit phase delays on the various actuation stage residuals (L1, L2, L3) and a zero pair on the magnitude residual of the L1 actuation stage to appease the calibration gods. The L2 and L3 actuation magnitude weighted mean residuals were already flat, so I did not have to fit them. This gives us a good idea of what our systematics look like for actuation. Slight phase delays on all at 100 Hz, and large deviation for the L1 stage magnitude. I will use these results to "correct" systematic error in our model by making a puesdo-model with the systematics included and comparing the two. To do: 1) Get realistic values for kappa uncertainty 2) Apply systematic "corrections" to a pseudo-model and compare with actual model 3) Make correct A_pu calculation corrections from Mathematica notebook 4) LLO
