Report table about all deviations is generated by the python script processing the metrology file. Large deviations exceeding standard precision >3σ(RMS) indicate on problem with measurement. A few corrections are usually applied for each metrology file.
Calibration file
In this section we discuss requirements to the geometry alignment parameters and describe chosen file format.
...
CalibManager under the tabs Geometry / Metrology has a GUI which processes metrology file and generates the calibration file like shown below for CXI-like CSPAD with moving quads (see example of file: geometry/0-end.data)
| Code Block |
|---|
|
All lines started with hash “#” are comments, which are also accessible through the program interface as a dictionary. XPP-like CSPAD with all sensors attached to the same plate is measured as a single detector. Its content part omits quads

Content of CSPAD2x2 geometry file consist of data for two sensors only:
