Abstract
We discuss the problem of assigning an effective temperature to models of stellar evolution in the Wolf-Rayet stage. We conclude that it is best to use models with different velocity laws depending on the stellar temperature. We follow the most simple approach and propose to use a standard law with Beta = 1 for the cooler and Beta = 2 for the hotter Wolf-Rayet stars. We present energy distributions from non-LTE model calculations with a Beta = 2 velocity law. The new calculations together with published results based on Beta = 1 allow one to synthesize realistic spectra of starburst regions. The flux tables are available in digital form from the authors.
