Abstract: Among the 120,000 objects in the Hipparcos catalogue, 235 were fitted with an orbital model, i.e. with up to seven additional parameters with respect to the default single star model. In their quest for the orbital inclination, spectroscopists promptly realized how useful the Hipparcos data could be. Besides the original 235 systems, most Hipparcos entries with a spectroscopic orbit (extrasolar planet or stellar companion) have now been re-processed. Not all these revised fits were fruitful. Some were even awful. We present a survey of all the areas where the Hipparcos observations have been fitted with an orbital model so far.
