*Note: There is *always* one transitor fault on the right septa (bigbite powersupply).

*Note: IHWP1 flips the beam helicity.  IHWP2 is passive (actually a full wave plate) and will not flip the helicity.  The status of both should be recorded. The epics var for IHWP2 is IGL1I00DIOFLRD :13056 means the passive wave-plate is in. 8960 is out..
