OMC alignment slider calibration

Hugh, Sheila

We noticed that the OMC suspension sliders aren't calibrated, so we did a quick check by moving 100 slider counts in pitch and yaw and looking at the DAMP IN.  We found we got 21 urad of pitch for 100 counts and 9 urad/100 counts in yaw.  So the OMC suspension calibration should be 4.76 counts/urad for pit, and 11.1 urad/count for yaw.  

I updated the slider gains and the current offsets.
