    • Lessons learned from SPHERE for the astrometric strategy of the next generation of exoplanet imaging instruments 
      Maire, Anne-Lise; Langlois, Maud; Delorme, Philippe; Chauvin, Gael; Gratton, Raffaele; Vigan, Arthur; Girard, Julien H.; Wahhaj, Zahed; Pott, Jorg-Uwe; Burtscher, Leonard; Boccaletti, Anthony; Carlotti, Alexis; Henning, Thomas; Kenworthy, Matthew A.; Kervella, Pierre; Rickman, Emily L.; Schmidt, Tobias O. B. (Spie-Soc Photo-Optical Instrumentation Engineers, 2021)
      Measuring the orbits of directly imaged exoplanets requires precise astrometry at the milliarcsec level over long periods of time due to their wide separation to the stars (greater than or similar to 10 au) and long orbital ...
