- 2013-12-10-Quad-MEC-Metrology.txt - text version of this file
- 2013-12-10-Quad-MEC-Metrology-corr.txt - text version of corrected metrology file.
New metrology file from 2013-12-20
- 2013-12-10-Quad-MEC-Metrology-improved-Z.xlsx - file from Gabriel Blaj with corrected z,
- 2013-12-10-Quad-MEC-Metrology-improved-Z.txt - text version, the same corrections are applied in x,y coordinates for point 4 and 18
Procedure
- Use script procOpticalAlignment.py for quality check and to look at constants for center and tilt
- Plots for non-corrected quad and difference between corrected and non-corrected metrology:
