Abstract: The sphere partition function is one of the simplest euclidean gravity computations. It is usually interpreted as count of states. However, the one loop gravity correction contains a dimension dependent phase factor, iD+2, which seems confusing for such an interpretation. We show that, after including an observer, this phase gets cancelled for the quantity that should correspond to a count of states.
