VizieR Online Data Catalog: SgrA* orbital motions with GRAVITY (GRAVITY Collaboration, 2018)
Abstract
The GRAVITY instrument combines the four 8m telescopes of the European Southern Observatory (ESO)-Very Large Telescope (VLT) interferometrically for 3 milli-arcsec (mas) resolution imaging and ~20-70microarcsec (μas) astrometry in the K-band (2.2μm) continuum.
