Abstract

The spectra of a number of reportedly sharp-line B, A and F stars havebeen observed in a 60-Å window with a resolving power of 120 000.As a first step in analysis of these data, the spectra have beensynthesized to see how well simple models fit. The informationobtained from both successful modelling and from discrepant fits isdiscussed.
