keyword=HARP scan at x = 3.8Here is HARP scan for run 1172 (CODA run 2009), see fig 1.
Epics says X,Y = +3.8, 0.
Spot says +3.4,0 (see 2nd plot)
HARP corrected says [2.8,0] (sign calib is different, see below)
Here is result of 'scanner' code on gougnaud account:
Survey offsets: X(5)=-0.07 Y(5)= 0.08 X(6)=-0.45 Y(6)=-0.23 mm
dz4A = 7345.00 dz4B = 2214.00
