Next: Double-lined spectroscopic binary Up: Fit scenarios Previous: Fit scenarios Contents . ... The reason for not choosing the mass of the primary is that with decreasing primary mass, the situation is asymptotically reached where the primary settles on a Keplerian orbit of a planet sized body and its velocity amplitude does not increase anymore. ... If, after fitting, the corresponding velocity amplitude is desired, one uses the modelk function, e.g. PRINT, MODELK(' A'). ...
