• It is clear that blind application of geoptimizer may cause >1 mm offset of panels in x-y ... 
• It is suggested to use geoptimizer for panels with fixed center and panel orientation in (x,y) from optical metrology and apply optimization for  z coordinate and off-plane tilts. Z coordinates were not measured correctly in optical metrology.
• Next optical metrology is expected to be with precise (~10um) Z measurement.
