Abstract
Given any two almost orthonormal systems A and A of unit vectors in a Hilbert space
X of the same cardinality, there exists a norm preserving almost isometry F of X so that
F(A) = A. It follows that to every almost orthonormal system there corresponds a system of
almost coefficient functionals.
