Took setpoint and cycled. Mismatched already, so we may choose to swap the card when there is time.

Generated CED based lists of correctors, split into ones with readbacks in mA and A for sake of comparison, and ran myStats on the PVs for current and noise. The noise PV is in bits, and the corresponding conversions to mA are detailed in the pictured help file.

The dips are only 1 mA but it's awfully strange looking. It has a period of about 3 minutes. I found this by running myStats on corrector noise alarms.
