Oh, and the shiftlog say (bracketing those  run numbers)

General

MCR called to tell me that they had reset the CDev server, however our magnet 
current alarm state is still red. The magnet is actually fine, so we will 
keep running and just keep an eye on the magnet currents.

SlowControls

Magnet current readings in slow controls fixed after CDEV reset during the 
night.

So, easiest is to mark all runs from 19158001-19158020 bad.  They are likely
not reconstructed correctly with the assumption of a gigantic magnetic field.
You may see quite an interesting momentum spectrum....
