Locked up the HEPI on HAM1 this morning. Attached is a plot of the IPS local and calc'd cartesian trends. The IPS here are in counts and they have a calibration of 655 counts per mil. The V4 trend still has a slope to it but I don't think it will go too far. I'll try to look again later. Meanwhile please use the numbers at the beginning of the plot as a reference. The IPS show a step at 8am (wasn't me!) but it is pretty small. The largest shift of the IPS from before the step to after the lock is < 200 counts = ~8um. The X Y & Z trends are in nm and max shift is 3000nm. The rotational trends are in nanoradians although I dispute the signs given right-hand-rules. The largest rotational shift is about 1000nrads.
