Single-lined spectroscopic binary with astrometric orbit

Add the remaining astrometric orbital elements to the fit parameters, and vary the secondary mass only. If you have a measurement of the parallax, say from the Hipparcos catalogue, you can add this measurement using the set_parallax procedure. In this case, you may add also the primary mass to the fit parameters as the system is now constrained just like a double-lined spectroscopic binary.
