Below are phasemaps for the tip-tilts with both tilt and RoC removed. We have not used Koji's code; but tweaked the earlier code to remove curvature.
The RoC values matched approximately to that quoted by Gari Lynn ~700m.
The color scale for height are not the same for all mirrors.
SN1, SN2 and SN3
SN4, SN5 and SN6
