Before lunch I got the sign off on the Optical Table position from IAS (Jason;) I expect you'll see an entry from him shortly. This was preceded by an elevation survey performed by myself and GregG: Our initial level had an 11mil runout about 4mils low per target (D1100398/E1000403). We did a couple small large Spring adjustments and finished at <8mils runout at -220.1mm average elevation Gz (0 error from spec.) After IAS was done, I activated the CPS, recorded locked positions and then unlocked the IAS. I repeated the lock and unlock recording the CPS all around. The largest change observed was <1200cts or 0.04mm, comfortably under our <1600 cts max lock/unlock change. WHAM6 has dummy payload on viton suitable for testing and is ready for doors. One final thing--conferring with Bubba/Apollo: I will lock the HEPI this afternoon and will not install HEPI electronics. Will keep the Dial Indicators in place to monitor HEPI position--please respect these.
