The 8 coefficients for MIMO tilt decoupling have been installed. Since we don't have an alignment matrix like in the ISI, I installed the product of the Local to Cartesian Position Sensor matrix and the tilt correction matrix.

Data has bee taken to check the decoupling results, both for the matrix resulting from SISO calculations and from the MIMO calculations (see yesterday's log for details)

The figure attached shows that the tilt horizontal couplings has been reduced to the order of 1e-3 for all 4 transfer functions (on the left of the vertical gray line, and under the horizontal one).

X to RX results show why MIMO calculation is slightly better. The effect could be larger if the RX to RY couplings were higher on other units.

We'll review these results at tomorrow's testing meeting, and will likely start working on a procedure to automate this process.
