Due to the HEPI Vertical Actuators being left locked down by an Assembly Tech, the final position numbers for the BSC8 platform I report in aLOG 2150 are not accurate.
I removed the locks this morning and I see a little movement of the system.  The motion is still not large but best to report it.

I now see a 9mil tilt down from SE to NW.  This is a 60µrad tilt and on the BSC optical Table at 77"φ, this would be a 4mil or 0.1mm tilt, if it remained a rigid structure which it isn't when unlocked.  It is however in the same direction of the tilt of the optical table I observed on Jan18.  Result, a 0.2mm tilt has become a 0.3mm tilt.  Does anyone want me to attempt correcting this?

Translation: There is a .005" shift South & a .009" shift West.  As I page back through the aLOG for IAS notes, I'm pretty sure we are nowhere near hitting tolerances for position remaining within .2mm transverse and <1mm longitudinal.

Rotation (Yaw) We translated 10mils South on the East side and just 2mils on the West side for a 60µrad CW rotation.  In aLOG 2069, Doug reports a 10µrad Yaw but I don't know the direction so giving us either a 50 or 70µrad CW Yaw.  Does anyone want me to correct this?

The corrections with HEPI are not easy as the Actuators are attached and they invariably pull or push the system around at these mil scales.
