The test of unplugging coils of mirror actuation has been performed at NE. The aim was to have a good lock using WE, in order to unplug all the NE coils at the same time, but we discovered that it was too glitchy. So we decided to unplug a pair of NE coils at a time, keeping the lock on the other pair. The eventual removal of common noise was not appreciable (fig 1). For a precise evaluation, the gps are:

gps1=1226317618;dur=300; UR DL unplugged

gps2=1226318168;dur=160; UL DR unplugged

gps3=1226310868;dur=300; clean data (relative to a previous lock)
