CSPAD geometry

Recommended software to access pixel geometry and produce image is described in Detector Geometry.

Deprecated packages

There is a couple of packages which reconstruct CSPad CSPAD pixel coordinates and images developed in C++ and python code;

• C++-based package: Psana Module Catalog - Old.
• Description of C++ package supporting calibration types: CSPAD Geometry Software (depricated).
• Python-based package:
  • CSPad image producer in Python (DEPRICATED)
  • CSPAD pixel coordinates and image producer in Python
