Today we moved WFS2 back to its original position and moved the second lens after the steering mirror. The combination without a second lens gave a beam too small. The new measured alignment matrix is

Sensing matrix for PIT was:
WFSA = +0.411*POS -5.483*ANG
WFSB = +1.269*POS - 3.783*ANG

Sensing matrix for YAW was:
WFSA = +0.036*POS + 1.962*ANG
WFSB =-0.431*POS + 3.265*ANG

The inverse matrices are:
PIT={{-0.7002, +1.0148}, {-0.2349, +0.0761}}
YAW={{+3.3830, -2.0329}, {+0.4476, +0.0373}}
