H1 HAM3 HEPI Actutors Attached & Released--IAS says OK! Prt Duex
OK now we have all the HEPI Actuators attached & released at the correct elevation and IAS has signed off on the position. Elevation & level is 0.1mm below nominal of -250.5mm (wrt LIGO Global) with a +-0.1mm levelness. Attached is my field notes of the final dial indicator readings and the level survey-enjoy. Thanks to Mitchell & Jason

I misspeak above where I say wrt LIGO Global. The number above, -250.5mm is the LIGO Global elevation corrected to the local leveling field. The HAM ISI Optical Table is positioned to -252.9mm. 2.4mm is the correction to local level hence the -250.5mm; please pardon the confusion. -H
