We consider a social-type network of coupled phase oscillators. Such a network
consists of an active core of mutually interacting elements, and of a
flock of passive units, which follow the driving from the active elements,
but otherwise
are not interacting. We consider a ring geometry with a long-range coupling, where
active oscillators form a fluctuating chimera pattern. We show that
the passive elements are
strongly correlated. This is explained by negative transversal Lyapunov
exponents.
