Analysis Results > Dynamics > Eigenvalues displays the following dialog.

It allows you to view eigenvalues (λ) and their derivatives such as periods (T), frequencies (f), and circular frequencies (ω). In addition, an error measure is calculated for each eigenvalue according to the following (see Ref. 1):
Error Measure =
