In contrast to CSPAD which data array shape is (N, 185, 388), the CSPAD2x2 data array has a shape (185, 388, 2); the memory pointer increment by 1 swaps the 2x1 sensor. The (raw,column)=(0,0) is located in corners 4 and 8 of optical measurement scheme for two 2x1 sensors, respectively.

Conversion between these data formats can be done in Python by methods

arrTwo2x1 = data2x2ToTwo2x1(asData2x2)
asData2x2 = two2x1ToData2x2(arrTwo2x1)

Geometry access

In 2014 new universal detector geometry software is implemented and documented in the Detector Geometry page. In this approach detector geometry calibration information is collected in a single file of type
