Resumen:
We show that the power-law decay modes found in linear perturbations of Schwarzschild black holes,generally called tails, do not produce caustics on a naturally defined family of null surfacesin the neighbourhood of $i^{+}$ of a black hole horizon.This null congruence thus yields a well behaved coordinate system both near the eventhorizon and at null infinity.
