If geometry_type=2, coordinates of the centre of the circle. If geometry_type=1 or 3, coordinates of the origin of the local coordinate system (X1,X2,X3) describing the plane polarizer. This origin is located within the polarizer area. Note that there is some flexibility here and the data provider should choose the most convenient coordinate system for the object, respecting the definitions of (X1,X2,X3) indicated below.
