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

...

• S1=S2, L1=L2 - the 2x1 sides should have equal length and width,
• D1=D2 - the 2x1 diagonals should be equal,
• dS1 = dS2 = 2*dL1 =2*dL2 - tilt angle should provide consistent deviation for all corners,
• dD=0, d(dS)=0, and d(dL)=0 - within precision of measurement.

...

• In Quad 1, pair: 3 mis-measured x and y - Use it as iscorrection is applied as discussed below.
• In Quad 3, pair: 5 mis-measured x and y - Use it as iscorrection is applied as discussed below.
• All other measurements are consistent within measurement precision about 10um
• Angles of 2x1 are in the range from -0.64 to +0.38 degree.
