keyword=run 7408 bpm3h09b dx oscillations - ffb correctors on though?

Similar plot to what Jim showed here: https://hallcweb.jlab.org/hclog/1011_archive/101118081623.html where dy is oscillating. In a followup entry, Riad showed that the FFB correctors were not actually on during this period to correct for the noise. I see similar behavious in run 7408, this time in dx while dy looks normal. I plotted the same variables for the FFB correctors, although I am not sure what the typical size of the signals should be (the y scale for each is 200, I just offset them for viewing), but at least they are not flatlined. Run 7408 was taken 11/21/10 from 17:27 to 18:29.
