H1 HAM2 ISI Optical Table set to Elevation & Level--Ready for IAS
Corey, Mitchell, Hugh We set the Optical Table in WHAM2 at -252.9 (E1000403) + 12.5 (T1100187-to correct for X-arm slope[local gravity plane vs LIGO Global Frame])= -240.4mm below the center of BSC2 where the local level and LIGO Global cross zero. The Optical Table is level to +-0.2mm. The HEPI remains floating and is ready for Initial Alignment horizontal adjustment.
