    Get it yourself first - Mr. Malik is correct, at least in the
terminology used in image processing & vision(1), computer
graphics(2), and planetary imaging(3). Line pair separation and visual
angle subtended by the smallest resolvable feature (not SOLID angle)
are the usual measures. Don't get on your high horse so quickly.
