- Number of rows x columns = 185 x 388. (In DAQ notation of rows and columns is interchanged...)
- Most of pixels have size 109.92 x 109.92 um*umum².
- Gap between two ASICS is covered by the two rows of elongated pixels with size 109.92 x 274.8 um*umum².
- Two versions of sensors have different dimensions between corners, so it is reasonable to define pixel coordinates w.r.t. the sensor center.

Software supporting CSPad geomtry
There is a couple of packages which reconstruct CSPad pixel coordinates and images developed in C++ and python code;
- C++-based package: Psana Module Catalog.
- Python-based package: CSPad image producer in Python.
Other useful documents: - Description of C++ package supporting calibration types: Psana CSPad Geometry.
- Note about organization of the calibration database: CsPad calibration in translator.
