Sažetak
We discuss the problem of the normalisation of stellar spectra obtained through spectral disentangling of a time series of spectra of a double-lined spectroscopic binary star and describe our disentangling code FDBinary. We consider in detail the application to the case of component stars with a time-indipendent flux ratio. In this case the component soectra are uniquely determined only up to a constant term. Additionally, due to deviations between the data and the model assumptions, the component spectra may be distorted and present ondulations in the continua. Based on the particular way of handling of singularities in the least-squares fit implemented in FDBinary we formulate a practical procedure intended for proper normalisation of the component spectra.
