    2424To get the precise position of the cylindre, it is useful to introduce a projection circle, using in '''uvmat''' the menu bar command Projection '''object/ellipse'''. In '''set_object''', select '''!ProjMode=''''none', so that the line is just used as a marker, without projection operation. Set XMax=1, YMax=1, the radius of the circle, and the coordinates (1.69, 4.05) of the centre in the table '''Coord'''. Then press '''REFRESH'''. To optimise the visualisation, zoom in and increase the image contrast to MaxA=100.

    26 To shift the coordinates, activate in geometry_calib the menu bar command '''!Tools/Translate points''', and fills  (x=-1.69, y=-4.05) in the edit box which pops up. the phys coordinates of the calibration points are then shifted, and a new calibration put the cylindre centre at the origin (0,0).
