An observer at constant proper acceleration in the Minkowski vacuum detects a thermal response at this temperature. The associated <Rindler coordinates> separate the observer's accessible wedge from a horizon. This is an observer-dependent particle/detector response, not an assertion that inertial observers measure a thermal bath.
