9. Jul - SepFeb – May Jun CERN, 169/R-004 ETHZ, Messekeller (Calibration Base Room) Data used to develop and debug the analysis software Precision and accuracy evaluation Measurements

10. Jul - SepFeb – MayJun 1.Minimum edge points (for each edge): increases the robustness. 2.Width of Region Of Interest (ROI) window: increases precision avoiding the out-of-focus area. 3.Height of Region Of Interest (ROI) window: helps when the wire is depicted inclined. 4.Maximum residual: increases precision discarding outlier pixels w.r.t. the fitting line. 5.Canny threshold: increases the robustness in case of noisy images.
