Sažetak
The complete set of orbital elements of binary and multiple systems can be only determined from complementary observables. In spectral disentangling the orbital elements are optimised along with simultaneous determination of the individual spectra of components. Therefore, a posteriori combination with some other observables, i.e. astrometric measurements or historic RVs is principally incorrect. With advances in the instrumentation more and more binary and multiple systems are spatially and spectroscopically resolved which makes the solution of orbital elements more firm. Following this advances, we have developed a wrapper with optimisation routine which enables spectral disentangling of time-series of spectra with the constraints from interferometric (astrometric) measurements.
