center- x, y, z center position of each 2x1 for all quadrants. Comes Obtained from optical measurement.center_corr- additional manual correction to the center parameter. Can be applied if the optical measurement has (non-)obvious problems.marg_gap_shift- margins, gaps, and shifts between quads, as explained below. Comes Obtained from image-based tuning.offset- x, y, z coordinates for 4 quads. Fairly-reasonable assigned before tuning of theoffset_corrandmarg_gap_shiftparameters.offset_corr- additional correction to the offset. Comes from image-based tuning.quad_rotation- 4 quad rotation in n*90 degree. Comes from basic geometry.quad_tilt- 4 quad tilt in fractional degree. Has never been used. In latest optical measurement is accounted through the global 2x1 coordinate measurement in the detector.rotation- 8 2x1-rotation angle for 4 quads in n*90 degree. Comes from basic geometry.tilt- 8 2x1-tilt angle for 4 quads in fractional degree. Comes from optical measurement.center_global- x, y, z center position of all 2x1 in the detector. Obtained from optical measurement for XPP-type detectors, and can be evaluated from other parameters or image-based tuning for CXI-type detectors.

center_global
Tail of the path: center_global/<run-range>.data
Parameters: x,y,z coordinates of all 2x1 centers in the detector in units of pixel size (109.92 um).
As usually, the matrix-style of the coordinate system is used:
