Abstract

The moment method seems to be suitable for determining the pulsation parameters of early-type stars but line profile variations are by no means staightforward to interpret (Waelkens and Aerts, this volume). It is clear that we have used only part of the information contained in the moments. A future development will be the construction of a discriminant which includes all significant information given by the moments and does not rely only upon a few leading terms.
