Results of OPLEV charge measurements (June, 24 - July, 06): Charge at the ETMX and ETMY is less then +/-10V. ETMY seems slightly negatively charged (about -3..-5V). We haven't see charge growing or significant changing of charge at ETMs over this time. 

Plots in attachment:
a) ETMX, ETMY - all measured charge data points (include today's measurements)
b) ETMX, ETMY mean value of charge for each the day and it's standard deviation + and weighted mean and weighted variance of measured charge for each day.
