VLTI/GRAVITY differential astrometry of binary star GJ 65 AB between 2017 and 2023

This dataset contains the VLTI/GRAVITY astrometric measurements of the relative position of GJ 65 B relative to GJ 65 A that were obtained between 2018 and 2023. These measurements are part of the analysis presented in the paper GRAVITY Collaboration et al. (2024, A&A, 685, L9). The columns contain the following information: mjd: modified Julian date of the observation. object: observed object (GJ65). raoff: angular separation from star A to star B in right ascension, in milliarcseconds. raoff_err: uncertainty on raoff in milliarcseconds. decoff: angular separation from star A to star B in declination, in milliarcseconds. decoff_err: uncertainty on decoff in milliarcseconds. radec_corr: correlation between raoff and decoff.
