  It is shown that probability densities of finite-time Lyapunov exponents,
corresponding to chimera states, have a characteristic shape. Such
distributions could be used as a signature of chimera states, particularly in
systems for which the phases of all the oscillators cannot be measured
directly. In such cases, the characteristic distribution may be obtained
indirectly, via embedding techniques, thus making it possible to detect chimera
states in systems where they could otherwise exist, unnoticed.
