OPLEV charge measurements, ETMX, ETMY

I ran the OPLEV charge measurements this morning for the both of the ETMs.

For ETMX the charge is still trending towards zero on all DOF/quadrants, LR and UR have the highest charge around ~60-70 V but they're trending down.

For ETMY the charge seems stable at or just above +50 V on most DOF/quadrants. The error bars are pretty big for EY, but the measurements all had great coherences. In each individual measurement none of the errors look very large except for LR which is broken/not used.
