Alignment parameters
The official place for CSPad alignment parameters is
/reg/d/psdm/<INSTRUMENT>/<experiment>/calib/CsPad::Calib<VERSION>/<CSPad-name>/<type>/<run-range>.data
The file name consists of the run range followed by the .data
, for example, 0-end.data
, 11-end.data
, 47-52.data
, etc.
All alignment parameters are splitted for 9 types:
center
- x, y, z center position of each 2x1 for all quadrants. Comes 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 from image-based tuning.
offset
- x, y, z coordinates for 4 quads. Fairly-reasonable assigned before tuning of the offset_corr
and marg_gap_shift
parameters.
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.
offset_corr
For individual quad position alignment use file: offset_corr/<run-range>.data

dZq0 dZq1 dZq2 dZq3

marg_gap_shift
For common gap and shift between quads correction use file marg_gap_shift/<run-range>.data
