In order to complete the individual data set for H1 SUS PR2's phase 2B testing, I attach the amplitude spectral densities of all stages of OSEMs. Tough to determine anything from these plots: - there's so many dang plots, - one is only comparing damping ON vs OFF, so you're only looking for "do the damping loops - Damp the resonances - Add any unexpected additional noise at any stage" but given those limited criteria, the answer is "looks fine..." Stay tuned for comparison with other spectra and a more concrete/final answer.
