Interpolated Ray Transfer Matrix (RTM, or geometry matrix), which provides transformation of the reflected light from each interpolation knot to the receiver (detector or head of an optic fibre). When convolving with an emission profile, the values must be interpolated to the emission grid and multiplied by the volume of the grid cells. The interpolated matrix is given on an array of interpolation knots of coordinates r, z and phi

channel(i1)/optical_element(i2)/geometry/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.
