The azimuth image

 

The azimuth of the c-axes refers to the image plane and runs clockwise from the vertical: up (North) is 0°, to the right (East) is 90°, down (South) is 180°. The azimuth file is monochrome (grey).

The chipmunk is a little darker than average grey, indicating c-axes striking more than 90°, i.e., NW-SE. Of course, the blue eye (remember ?) has an azimuth of less than 90°.
