We(Jim Greg & I) positioned the SEI (Support Tubes) to the correct elevation to put the Cartridge at the correct elevation and position, as best we could.

The vertical is set ~0.025" high (to allow for sag with 10000lbs added) to +1061.0mm.  Nominal height for the Support Tube bottoms would be 1060.4mm nominally putting the Optical Table at 1661.7mm.

We are left with some irreducible horizontal adjustments with the South side needing to go West 3mm and the North side needing to go East 1.5mm but the West and East sides only getting worse if those corrections are made and sitting well within 1/2mm of perfect.  I'll leave the position where it is.
