There is a very minor tilt at the lower right corner. (value 8.0)
Furthermore there is some curvature/aberration. The HFD value tend to increase the further away from the center. The nine value represent a 3x3 matrix of areas. The center is the best with 6.54. The corners are the worse. This result in the star shape rather then a square. See: http://www.hnsky.org/astap.htm#inspector
Hope this helps, Han

I am trying to understand those numbers as I just discovered this hidden feature in ASTAP. Thank you!
