  The Minkowski vacuum $|0\rangle_M$, which for an inertial observer is devoid
of particles, is treated as a thermal bath by Rindler observers living in a
single Rindler wedge, as a result of the discrepancy in the definition of
positive frequency between the two classes of observers and a strong
entanglement between degrees of freedom in the left and right Rindler wedges.
We revisit, in the context of a free scalar Klein-Gordon field, the problem of
quantification of the correlations between an inertial observer Alice and
left/right Rindler observes Rob/AntiRob. We emphasize the analysis of
informational quantities, like the locally accessible and locally inaccessible
information, and a closely associated entanglement measure, the entanglement of
formation. We conclude that, with respect to the correlation structure probed
by inertial observers alone, the introduction of a Rindler observer gives rise
to a correlation redistribution which can be quantified by the entanglement of
formation.
