		The inclination image (circular polarization)
		This inclination image is derived from the circular polarization image. The function relating the brightness of the image to the inclination of the c-axis is the sine-square (as shown below). Through this dependence (and the scanner calibration) one can derive the inclination directly from the grey values in the polarization image. As before, the inclination of the c-axes refers to the image plane and runs from above the image plane to below: above (Heaven) is 0°, horizontal is 90°, below (Hell) is 180°. The inclination file is monochrome (grey). If the circular polarization image and the rotation images are perfectly calibrated, the inclination images inca (from amplitude) and incp (from circular polarization) should be exactly the same. For the same reasons as before, the chipmunk is a little spotty,...   Left, from top to bottom: - inclination image (incp) of Black Hills quartzite - stereographic projection (note orientation !) and orthogonal representation of look-up table for inclination image - the spotty chipmunk...
