Attached are the usual long trends of the charge on ETMx and ETMy with the latest data appended.  The ETMx charge accumulation is still decaying towards 0, but not there yet.  The ETMy charge is also near zero in almost all 4 quadrants.  Kissel and I decided we will leave the signs of the ESD bias as they are for another week.  It doesn't look like the ETMx data from today was affected too much with the ISI tripped this morning (the SUS was still damped).
