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.
