WP 7364 -- Locked EndX HEPI this morning, pretty close to operating position, Z not so much.  Will leave this WP open until the HEPI is unlocked.

ETMX found in ISI DAMPED HEPI OFFLINE.  Took SEI guardian manager to DAMPED--this took the HEPI to Robust Isolated.  The HEPI was then locked onto its stops as closed to the Isolated position as possible: dX dY dRX dRY are all under 10um(urad), and dRZ is less than 200nrads. dZ is 83um but I figured this was the least significant dof for the upcoming task.  These di values are the difference from the nominal isolated position.  HEPIs for the BSC don't have a 'down' lock so it is difficult to keep it from squirting up as the sides are pinched into position.

Of note, when the ETMX Optical Lever was recentered on 15 Feb, it was done without the HEPI holding the nominal orientation.  Fortunately, Jim and I have debiased the HEPI position onto the DSCW springs and as you can see on the attached plot, the isolated/not isolated amounts to about 6 Oplev yaw plot units (urads?Yes urads).  Still, nominally, oplev centering should be done with the HEPI fully isolated (ISI not so important.)

The attached 3 hour plot has the HPI & SEI guardian states (chans 1 & 2), the OpLev Pit & Yaw (3 & 4), with the rest being the HEPI position residuals. Note the annotations showing the shift in the OpLev Yaw when the HEPI Isolates and the residuals go to zero.
