h1. Alignment procedure
Alignment procedure for CSPAD2x2 is very similar to CSPAD alignment for quads described in
[PCDS:CSPAD Geometry and Alignment].
The only difference is that CSPAD2x2 has only two 2x1 sensors, that makes everything much simpler.
h1. Optical measurements
Photos and charts with numeration of corners in otical measurements:
