Abstract
In the semiclassical analysis of black hole radiation in matter-coupled dilaton gravity, a one-parameter 'k'-family of measures for the path integral quantization of the matter fields is considered. The Weyl anomaly is proportional to the parameter k, but the black hole radiation seen by Minkowskian observers at future null infinity is k-independent.
