PR2 ringing at 1 Hz
Masayuki, Sheila
When we step the alignment sliders in pitch or yaw on PR2, we see 1 Hz ringing for 15-20 seconds.

Keeping an eye on PR2, took an osem spectra of the inmons and don't see anything abnormal in the suspension right now - but will keep investigating it if these oscillations returns.
