- pair 2: 1.7mm un-flatness in Z. Most likely point 13 Z=−1.76 is a wrong value, but there is no method to check...; do not care about Z for now
- pair 2: 0.8mm deviation in X: Correction to point 16: x−0.8mm; 44.63 => 43.83
- pair 5: 0.35mm deviation in X: Correction to point 24: x+0.35mm; 90.62 => 90.97

Geometry parameters
Parameters for center and tilt are available in
/reg/neh/home1/dubrovin/LCLS/CSPadAlignment-v01/calib-mec-2013-12-20/*/0-end.data
Summary
X coordinates are corrected for points 16 and 24
- point 13 Z=−1.76 is suspicious, but there is no hint how to correct... May be 2x1 is badly bent...
