Given a field vacuum state in a black hole spacetime, this state can beanalysed in terms of how it is perceived (in terms of particle content) bydifferent observers. This can be done by means of the effective-temperaturefunction introduced by Barcel\'o et al. in [1]. In Barbado et al. [2], thisfunction was analysed in a case by case basis for a number of interestingsituations. In this work, we find a general analytic expression for theeffective-temperature function which, apart from the vacuum state choice,depends on the position, the local velocity and the acceleration of thespecific observer. We give a clear physical interpretation of the quantitiesappearing in the expression, and illustrate its potentiality with a fewexamples.
