We study the stress energy two-point function to show how short distancecorrelations across the horizon transform into correlations among asymptoticstates, for the Unruh effect, and for black hole radiation. In the first casethe transition is caused by the coupling to accelerated systems. In the second,the transition is more elusive and due to the change of the geometry from thenear horizon region to the asymptotic one. The gradual transition isappropriately described by using affine coordinates. We relate this to thecovariant regularization used to evaluate the mean value of the stress energy.We apply these considerations to analogue black holes, i.e. dispersivetheories. On one hand, the preferred rest frame gives further insight about thetransition, and on the other hand, the dispersion tames the singular behaviorfound on the horizon in relativistic theories.
