With the Quad back on and things close back to fighting weight, the HEPI hang should be back to near or at final position.  I understand the payload should essentially be the same as before so with IAS looming we checked the Optical Table level with the Optical AutoLevel.

The ISI is locked but the lock/unlock position difference should be near ignorable.  That said final alignment/level checks should be done with the ISI unlocked.

OK, results:
Nominal elevation is 1661.7mm and the four shots taken average to 1661.65 with a spread of ±0.15mm.  The Optical Table is not 2000mm in diameter and we certainly were not observing at the far edge of the Table so this level is certainly not within the 100urad requirement.  We are likely double that.  I'd like to check it with the ISI free and with three equal sticks hanging on the table before we move anything.
