The 10x unbalance must be from somewhere else but the coils since all four coils on MCI, MCO, MCE are all healty. Diaggui data is on /users/VIS/190916/.
MCE
H1 @DC -45 @10Hz -74
H2 @DC -45, @10Hz -74
H3 @DC -45, @10HZ -74
H4 @DC -45, @10Hz -75
MCO
H1 @DC -50, @10Hz -81
H2 @DC -49, @10Hz -79
H3 @DC -49, @10Hz -75
H4 @DC -50, @10Hz -77
MCI

H4 @DC -46, @10Hz -77
unit is [urad/cts]; each coil to oplev PIT channel.
And yes, the beam doesn't seem to be at the center on MCO. It seems to move since this time. MCE is better, and we have no camera for MCI. See the attached photo.
