Sažetak
Disentangling of composite spectra is a promising technique for the analysis of double-lined spectroscoic binary systems. The technique makes use of a separation routine to extract model-component spectra out of a time series of observed composite spectra. Focusing on the differences between two possible approaches in the implementation of the separation routine, we compare the resulting limitations. We perform test runs on artificial data and cnclude that separation in the wavelength domain is more versatile in several aspects, while the computational efficiency of separation in the Fourier domain allows working with larger data sets which is beneficial in a fully-blown disentangling process.
