Scientific paper

In a few years astrometry with the Fine Guidance Sensor on Hubble Space Telescope will be replaced by Gaia, SIM, and ground-based long-baseline interferometry. Until then we remain a resource of choice for reliably sub-millisecond of arc precision optical astrometry. As examples we discuss 1) the uses which can be made of our parallaxes of planetary nebulae central stars, and 2) the determination of perturbation orbital elements of exoplanet host stars, yielding true companion masses.
