1 metrologyUpgrade VELO - RF shield 13/08/2014CERNMassimiliano Ferro-Luzzi 1 38 scans per data set:  6 longitudinal scans over each central bulgenr 1 to 6  6 transverse scans over each bulgenr 7 to 12  7 transverse scans over each necknr 13 to 19  repeat for other side thickness obtained from comparison of both sides I redefine "my axes"... Thickness by precise metrology Thanks to Didier Glaude
