Zusammenfassung:	A method for detecting perturbation of a physical system from a reference state associated with a reference parameter (omega0) to a perturbed state associated with a perturbed parameter (omega) includes firstly deriving the reference parameter (omega0). A reference vector (F) is then derived which describes the system's state at the reference parameter (omega0). A measurement-related vector (Z) associated with a perturbed state of the system is then subtracted from the reference vector (F) to provide an error vector (E). The error vector members are summed and normalised by division of a summation of elements of a vector (F') representing a derivative (f(omega0deltaomega)e) of a reference itself represented by the reference vector (F), the derivative (f(omega0deltaomega)e) being evaluated at the reference parameter (omega0). This provides a result equal to the difference (omega-(omega0) between the perturbed parameter (omega) and the reference parameter (omega0).
