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