We found the parallax to be dependent on the Gaia DR2 G-band apparent magnitude for stars with 13 < G < 18, where brighter stars have a lower parallax zero point than fainter stars. The distance to 47 Tuc was found to be 4.45 ± 0.01 ± 0.12 kpc, and for NGC 362 8.54 ± 0.20 ± 0.44 kpc, with random and systematic errors listed, respectively. This is the first time a precise distance measurement directly using parallaxes has been determined for either of these two globular clusters.","lang":"eng"}],"article_number":"132","oa":1,"_id":"15234","quality_controlled":"1","oa_version":"Preprint","publisher":"American Astronomical Society","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.1807.07089","open_access":"1"}],"article_processing_charge":"No","issue":"2","external_id":{"arxiv":["1807.07089"]},"intvolume":"       867","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"month":"11","scopus_import":"1"}
