To maintain a consistentreference system, the origin is located 194mm above this reference tube for the y − zplane since the corresponding module are placed underneath the other ones.y ′yxβx ′2 mFigure 5.5: Top view: Position of the CMT (square) on top of the Borexino watertank (circle). The coordinate systems of both the CMT (green) and Borexino (blue)are shown. They are rotated at an angle β with respect to each other.Table 5.1: Relative coordinates of the Borexino center within the CMT referencesystem.Value∆x∆y∆zβShift-4532.33 mm887.456 mm-9244.96 mm58.19 ◦73
