Some ASC loop bandwidths

I took step responses for some of our slower ASC loops by applying small offsets to the digital error points. Bandwidths are determined via a simple exponential fit to the error signal response (so in some cases, particularly for the faster loops, this is probably underfitting).

  Pitch [Hz] Yaw [Hz]
IM4 0.10 0.06
PRM 0.03 0.2
SRM 0.14 0.5

We evidently have great dissimilarity between pitch and yaw for some of these loops.
