		Checking the inclination image (cirpol)
		In order to check the calculated inclination image against the circular polarization image, the Lazy LUT macro (key C: "INC to CirPol", see appendix 2) is used. The histogram of the converted inclination image reveal an approximate sine relation between inclination and grey-value (Since NIH Image is based on optical density rather than brightness, the sine relation is inverted). The histogram is indicative of a texture which is random or nearly random with respect to inclination (not necessarily with respect to azimuth.
