keyword=missing wires in fpp front u
When there is a group of missing wires in FPP front straws, 16 wires in planes
1-3 or planes 4-6, it usually results from a blown fuse that supplies + or - 5 volt
power to a stack of 3 readout boards
In this case, it puts a false asymmetry into the front analyzer, so we lose
p_y from the front. Cx and Cz should be okay due to the helicity flip.
For the rear analyzer, there is no false asymmetry, but there will be in effect
a reduced efficiency for the events that are not tracked in the front chambers.
