Optical measurement
We use before-run4 optical measuremens from Chris:

Procedure and table of results
We calculate
S1 - 1st short side of 2x1
S2 - 2nd short side of 2x1
L1 - 1st long side of 2x1
L2 - 2nd long side of 2x1
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).
Everything, excluding <dS/L> and angle(deg), are in micrometers.
S1 S2 dS1 dS2 L1 L2 dL1 dL2 <dS/L> angle(deg)

- Problematic measurements are
- Quad 2, pair 6 - significantly different length of sides
- Quad 2, pair 7 - significantly different length of sides
- Quad 3, pair 5 - significantly different width and length of sides
- All other are consistent with each other within
+/-10um. - Angles of 2x1 are in the range from
-0.46to+0.44degree.
Configuration parameters
Configuration parameters are shown in number of pixels.
For 2x1 pairs in each quad
Coordinates of the 2x1 centers
- Use the same orientation as in optical measurement, center is calculated as an average of 4 corner coordinates
- All coordinates in pixels
