Detector description
channel(i1)/detector/geometry_typeINT_0D¶Type of geometry used to describe the surface of the detector […]
Type of geometry used to describe the surface of the detector or aperture (1:’outline’, 2:’circular’, 3:’rectangle’). In case of ‘outline’, the surface is described by an outline of point in a local coordinate system defined by a centre and three unit vectors X1, X2, X3. 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. In case of ‘circular’, the surface is a circle defined by its centre, radius, and normal vector oriented towards the plasma X3. In case of ‘rectangle’, the surface is a rectangle defined by its centre, widths in the X1 and X2 directions, and normal vector oriented towards the plasma X3.
