QC procedure and results
We calculate
S1 - 1st short side length of 2x1
S2 - 2nd short side length of 2x1
L1 - 1st long side length of 2x1
L2 - 2nd long side length of 2x1
D1 - 1st diagonal of 2x1 between corners 1 and 3
D2 - 2nd diagonal of 2x1 between corners 2 and 4
dS and dL are the deviations of the 1st and 2nd corner along the short and long sides, respectively. The sign of all dS are chosen in order to provide correct sign for the tilt angle (the same direction for all 2x1 sensors).
<dS/L> - the tilt angle of 2x1 averaged over two sides in radians.
angle(deg) - the same angle in degrees.
dD = D1 - D2
d(dS) = dS1 - dS2
d(dL) = dL1 - dL2
Quality check parameters for the perfect measurement:
S1=S2, L1=L2 - the 2x1 sides should have equal length and width
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.
Everything, excluding <dS/L> and angle(deg), are in micrometers.

Comparing deviations of dS1 and dS2, and dL1 and dL2, we found:
- All other measurements are consistent within +/-10um
- Angles of 2x1 are in the range from -0.56 to +0.41 degree.
- THIS IS THE MOST CAREFUL MEASUREMENT SO FAR, WHICH DOES NOT SHOW ANY PROBLEM IN THE QC.
