HAM2 and HAM3 Optical Lever Work

Checked out both HAM2 and HAM3 optical levers today.  No major problems with either, only thing was the transmitter telescope pitch/yaw adjustments for both oplevs were not locked down so they both had significantly drifted (completely off the mirror, no return back on the QPD).  This was rectified; both oplevs were realigned and locked down.  Beam profiles and power measurements were done for both (will attach a comment tomorrow with this info, left it all in the LVEA...).  New calibrations were NOT attempted as this requires moving the ISIs; will need to find a window between commissioning work (maintenance Tuesday perhaps) and sit down with someone from SEI to do this.
