Took Charge Measurements at EX and EY

I took charge measurements at both ends today, they finished around 12:50 local. I'll post plots soon.

There were a few weeks that were not placed into the long trend, but a large majority of the data seems to be bad. I took out what I saw was obviously bad but the error bars are still huge on many of the points. Plots are attached but it definitely needs a second look hopefully tomorrow.

Note, I think it is time to change the sign on both of these ETM ESDs.  The ETMx has now migrated ~20-30 volts away from 0, albiet at a slow rate.  The ETMY sign flip from last month needs to be investigated since it seems that charge is still growing (slowly) there.  More to follow.
