These two fields are located at ~12' from the centre of the globular cluster (in the West and South-West directions) and were imaged in filters from the ultraviolet to the infrared. Both fields were observed at two epochs separated by about 2 years that were used to derive proper motions and to compute membership probabilities.", "revisions": [ { "version": "v1", "updated": "2021-07-19T09:52:37.000Z" } ], "analyses": { "keywords": [ "hst large programme", "omega centauri", "external fields", "state-of-the-art catalogue", "remaining parallel fields" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable" } } }
