What are anamorphic lenses and how is the principal axis defined in them considering their different magnifications in different planes?

The directions of the three mutually orthogonal unit vectors $\hat{\mbox{\boldmath$\omega$}}_i$ define the three so-called principal axes of rotation of the ... Jan 2, 2010 ... ULS is the same as the MINRES method described in Harman's factor analysis book. The equivalence is pointed out e.g. by Joreskog (2007) in the ... Dec 30, 2020 ... The coordinate system for which the inertia tensor is diagonal is called the Principal axis system which has three perpendicular principal axes. These basis vectors are known as the principal axes (or directions) and the non-zero tensor components as the principal values. This frame is based on the lunar principal axes, and differs from the Moon ME frame by about 1 km at the lunar surface.
