Centers of mass, lengths of semiaxis and eccentricities are rotation invariants.
For non rotation symmetrical aberrations the geometry of the PSF can be very complicated because the centers of mass, the eccentricities and the axis orientation of [V.
In this paper the authors proposed alternative methods for calculus of position of the central axis and the centrifugal moments, based on the coordinates of centers of mass.
