The error image

There are a number of causes that lead to the errors associated with the curve fitting of the brightness function:

the inclination itself: 0° and 180° inclinations tend to have larger errors than 90° inclinations (compare error image and circular polarization image,left)

the superposition of two differently oriented grains along oblique grain boundaries

the presence of biaxial minerals such as feldspar...etc.

Taking the inverse of the error image allows one to discuss the so-called quality image...

Left, from top to bottom:

- error image of Black Hills quartzite (black = large error, white = small error)

- circular polarization image of Black Hills quartzite

- the faulty chipmunk... (black = large error, white = small error)
