A critique of disentangling as a method of deriving spectroscopic orbits.
HYNES R.I. and MAXTED P.F.L.
Abstract (from CDS):
Multiple sets of synthetic spectra of OB-binary stars are used to test the suitability of disentangling for deriving accurate spectroscopic orbits. Given a set of spectra with broad phase coverage and sufficient total integration time (almost independent of the number of spectra), it appears that disentangling yields accurate and reliable semi-amplitudes of the spectroscopic orbits (other parameters being fixed).
Method. for estimating the uncertainties on the derived semi-amplitudes are investigated.
