Attached are a couple trend plots to show the history of the HAM4 alignment.
HAM4 ISI Optical Table was aligned late January and the Actuators finally attached Early March.  The first plot shows the electronics coming on 7 March and the zeroing of the IPS & Locking 11March.  The doors were installed then to work on HAM5.  The Pier Pods were turned off briefly towards the end of March.
The second plot just overlaps the first plot by a day or so and switches to the Cartesian basis.  The matrices were loaded 28 March (aLog 11078) making the Cartesian units valid.
Pretty quite after that until 11/12 April when TFs De-Stress the system and things settle into a new position (more steady/long lasting?--Who knows)

Bottom line--The main thing is the 80 urads of CCW yaw.  THis of couse won't take much for SUS to correct during up coming alignment but the position loops are still not working.  But, -80urads will be the HEPI 'zero' for HAM4 Rz.
