Note

Chris informed me that in this measurement the detector was rotated by 180 degree, that requires to interchange of Q0 with Q2 and Q1 with Q3 parameters. It was done in 2013-01-24-CSPAD-XPP-Metrology-standard.txt-standard file.

It is clear that Quad 2 p.21 (12 in standard numeration) is 1000um off. It is corrected in the 2013-01-24-CSPAD-XPP-Metrology.txt file
