- Quads are aligned individually using their natural coordinates as in optical measurement (top-left corner is an origin, nearest point to the beam spot).
- Sensors are aligned based on their center point position from optical measutement.
- Center coordinates were float with precision of 1 um.
- Additional hand-made offset is applied based on deviation plots.
- Tilt angles were taken into account.
- After sensor translation and tilt rotation coordinates are rounded to integer numbers in order to insert everything in 2-D array.
