• 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 um².
• Gap between two ASICS is covered by the two rows of elongated pixels with size 109.92 x 274.8 um².
• Two versions of sensors have different dimensions between corners, so it is reasonable to define pixel coordinates w.r.t. the sensor center.

Optical measurement

Optical measurement is conducted by Gabriel Blaj. Detector or its quad is installed on microscope table and 3-d coordinates of all 2x1 sensor corners are measured with precision about 8um (RMS) in x-y plane. All corners in the measurement are numerated in arbitrary order. It is expected that numeration order should be the same for different measurements. This procedure depends on CSPAD construction;
